53bbdc7425 Remove obsolete bionic/android support
The bionic libc support was out of date and relied on downloading
binaries from the internet. It was already marked as obsolete. Now that
the 1.25.0 release is out it can be completely removed.

cc6b7fad46 Retire obsoleted milestones
... and the code dependent on them, after the latest wave of obsolete
package removals. This concludes the glorious history of the original
uClibc (non-NG) with lots of kludges removed.

There was a choice here, whether to call the resulting libc "uClibc" or
"uClibc-ng". I opted in favor of giving uClibc-ng the recognition it
deserves, although it had some ripple effect in the ct-ng code.

beae27d87b arm: Disable context functions for Thumb
Similar to commit 57679b5e ("Disable context functions for Thumb") when
building for thumb we need to unset UCLIBC_HAS_CONTEXT_FUNCS.

Fixes #1397

57679b5e61 Disable context functions for Thumb
They're written in ARM dialect, and `ldmia r14, {r14, pc}` is not accepted in T2
encoding. GCC8 changed the list of multilibs for arm-*, which now includes a
variant with CPU that supports T2 but not A1 encoding.

1029dcf91a Fix ARM32 name for android
Must have eabi suffix for GCC to accept it. Also:
- We only have one glibc now, no need to account for eglibc.
- Rename aarch64 samples, eabi suffix does not apply to them
  (and ct-ng saveconfig was saving them into a different directory).

Fixes #772.

f2ffdf798d First stab at multilib/uClibc.
Create a separate 'libc_backend_once', install headers into a
subdirectory (different sets of headers are installed for 32- and 64-bit
architectures), and create a symlink for the dynamic linker location
expected by GCC.

3ebc5d0c1e libc/*.sh: Deprecate libc_check_config step.
This step was only used in uClibc. However, with upcoming multilib, the
config management will have to be done for each variant differently,
anyway.

uClibc was the only user of libc_check_config step, as well as
CT_CONFIG_DIR directory. Retire these.

Two other clean-ups in uClibc.sh:
- KERNEL_HEADERS check seems to be bogus, this config option is not
  present even in 0.9.30 - which is not supported already.
- SHARED_LIB_LOADER_PREFIX was renamed to MULTILIB_DIR in 0.9.31,
  according to ChangeLog - and MULTILIB_DIR is passed from command line
  instead.

34ecc718d9 arch/all: Add common function to return multilib target
This code was abstracted out of Cody P Schafer's multilib patch.
It doesn't seem right having architecture dependent code in a
specific libc implementation script. So this patch breaks it out into
scripts/build/arch/<arch>.sh in a function:

  multilib_target_to_build="$(CT_DoArchMultilibTarget 'multi_flags'
'target-in')"

Note that this function gets called on each multilib variant with
different sets of compiler flags supplied in 'multi_flags'. The caller
will first filter the flags so that there is no conflicting flags (e.g.,
no '-m32 -m64') supplied.

Changed by Alexey Neyman:
- make option analysis check specific option rather than match global
  options string as a whole. Moreover, old code did not handle multiple
  options in the same multilib, e.g. '-m64 -mlittle'.
- fixed substitutions in powerpc.sh (*le variants did not match the
  pattern in the shell parameter expansion)
- make s390.sh actually apply the flags it gathered from the options.
- straighten the spaghetti in x86.sh by setting two flags, arch & abi.
  Also, do not depend on "gnu" being the last part - we can have
  '*-uclibcx32', for example.

52260ccebb libc/musl: add musl-libc support
This patch adds initial support for musl-libc.

Musl-libc versions currently supported:
* 1.0.3 (Stable)
* 1.1.3 (Previous Mainline)
* 1.1.4 (Mainline)

Futher improvements are needed.
* gcc-4.9.x has issues (Might be fixed in musl-1.1.4).
* Multilib support is needed.
* Checks to make sure paths are correct.
* Move to 2-step gcc build. 3-step build is not necessary.

150f500426 arch: allow adding a suffix to the arch-part of a tuple
For some architectures, it is legit to have an alternate value in the
'architecture' part of the tuple. For example:
    armv5te-*
    armv7a8-*

Besides, some packages expect the tuple to reflect the arch variant
(eg. openMPI) to detect the variant's capabilities (eg. atomic
primitives).

This patch adds an option for the user to specify a suffix to be added
to the arch-part of the tuple.

c1d673203d arch/arm: add option to use *eabihf tuples
Toolchains that use the hard-float ABI now are to be denoted by a tuple
ending in *eabihf, while the prevbious *eabi is now an indication that
the toolchain uses the softfloat ABI.

This is purely a cosmetic thing, for distros to differentiate their
hardfloat-ABI ports from their softfloat-ABI ports.

(note: softfloat ABI does not mean that it is using softfloats; it can
be using hardfloat instructions, but using the softfloat ABI).
