53892de14c config: fix recursive deps
The latest kconfig stuff is more stringent when it comes to validating
the dependency of the symbols. It is no longer possible to have a symbol
depend on itself (such as our construct for arch/cc/libc/... was doing).

Fix our generated-file infrastructure to avoid these situations when the
new kconfig stuff will be merged (in a following changeset).

linker during the toolchain build.

b93e67f07c libc/glibc: add fortify option
By default, recent versions of glibc and eglibc will build some
functions that take format strings (eg. printf, syslog...) with
run-time checks against some format string attacks. This is
called a fortified build.

Unfortunately, this fails somehow while building the instrumented
version of syslog, with some kind of circular dependency...

Disable fortified builds by default, and hide the enabling option
behind EXPERIMENTAL for daring users...

1838bb1f15 libc/glibc: add option to force unwind
We make it an option, as not all combinations of architectures
vs. compiler vs. glibc/eglibc exhibit the issue. Mostly visible
on old glibc versions, it seems...

This is a missing part from the glibc/eglibc merger... :-/

c5462c814f libc/glibc: get rid of the now obsolete CVS stuff
It's now been a while that glibc switched to git from cvs.
Get rid of cvs to download glibc; this will make for a good
cleanup before we add git support! :-)

33edeaa6a5 For glibc & eglibc, try to auto-select the ports addon for those
architectures that require it (curently, ARM and MIPS are known to).

a1828c87f3 Offer a single option for the glibc/eglibc add-ons selection, rather than hiding it behind a toggle.
If the list is empty, then there is no add-on. If the list is not empty, then there are add-ons.
