d7b4f0dbe3 glibc: nptl is default from 2.20, so dont add to addons_list
No longer recommended practice to use --enable-add-ons=nptl, so
for 2.20 and later (along with custom glibc), don't add the
CT_THREADS to the addons_list

edd01b7729 libc/(e)glibc: fix extra configparms
In case ${CT_LIBC_GLIBC_CONFIGPARMS} starts with a dash, printf will try
to interpret it as an option for itself, and will invariably flail in
panic as it does not recognise any of it.

Use a more robust solution, as suggested by Cody.

74d555b2c3 scripts: add support for building manuals
Add support for building the HTML and PDF manuals for the major
components.  Implement for binutils, GCC, GDB, and GLIBC.

Always build all manuals and install a subset.  Be explicit about the
subset to reduce the clutter and to avoid getting copies of common
manuals like bfd from all of the sourceware based components.  Downside of
being explicit is that you need to update it when a new component
comes along.

Build the manuals as part of the last GCC build, namely 'cc' for glibc
based ones and cc_core_pass_2 for baremetal.

2ea05ecaa7 scripts/libc: do not build add-ons by default
Currently, no --enable-add-ons option is passed to libc configure when
"$(do_libc_add_ons_list ,)" is empty, which makes configure automatically search
for present add-ons. In that case, all present add-ons are built, although
no add-on was selected by the user in the config. Moreover, this can make the
configure fail if some non-standard add-ons like eglibc-localedef are present.

This behavior also leads to an inconsistency from a user point of view between
the following cases:
 - LIBC_ADDONS_LIST="", LIBC_GLIBC_USE_PORTS=n and THREADS="none" in the config,
   which makes "$(do_libc_add_ons_list ,)" return "", so all present add-ons
   are built.
 - LIBC_ADDONS_LIST="", LIBC_GLIBC_USE_PORTS=n and THREADS!="none" in the
   config, which makes "$(do_libc_add_ons_list ,)" return the add-on supporting
   the chosen threading implementation, e.g. "nptl", so only this add-on is
   built.

This patch disables the building of all add-ons in that case.

It is still possible to build all present add-ons by adding --enable-add-ons to
LIBC_GLIBC_EXTRA_CONFIG_ARRAY.

6940a6c0eb glibc: Refactor startfiles/headers into do_libc_backend()
Refactor the contents of 'do_libc_start_files()' and 'do_libc()' into a
parameterized 'do_libc_backend()'. 'do_libc_start_files()' and 'do_libc()'
call 'do_libc_backend()' with either 'libc_mode=startfiles' or
'libc_mode=final' (respectively) so that the startfiles/headers and
the final libc builds are configured and built with the same options.

One example of where this is needed is when building a mips toolchain.
Previously, if you were building an n32 toolchain, you wouldn't have
noticed an issue, because if '-mabi' is not in CFLAGS, n32 is the
default:

http://sourceware.org/git/?p=glibc-ports.git;a=blob;f=sysdeps/mips/preconfigure;hb=HEAD

But when trying to build an o32 or n64 toolchain the build would
have failed. This is because (e)glibc expects "-mabi={o32,n32,n64}" to be
in CFLAGS, but was not previously provided in 'do_libc_start_files()'.
The build failure would happen in the shared-core gcc when it tries to
configure an n64 or o32 gcc with an n32 libc.

A simpler solution would have been to just add TARGET_CFLAGS to configure
in 'do_libc_start_files()', but this way makes configure and make
consistent for both steps.
