scripts: PARALLELMFLAGS is evil, rename

The reunification of the glibc/eglibc code paths exposed a nasty
bug in the glibc build: use of PARALLELMFLAGS breaks the build.

See the explanations in that bug report against FC6:

libc/glibc: commonalise assembling the list of addons

glibc and eglibc each have two very similar ways of building this list.

libc/glibc: use the common start_files procedure

Use the common procedure, shared between glibc and eglibc. This requires

But still build the full libc with the glibc-specific procedure. This will
be commonalised in a future commit.

libc/eglibc: move generic code to a common file

- add-ons list

libc/mingw: move content of do_libc_headers into do_libc_start_files

It is unnecessary to split C library preparation into two steps, as only
one really makes sense. So, do_libc_headers is bound to be withdrawn
short-term, in favor of do_libc_start_files.

mingw already had all its start files installation in do_libc_headers, and
do_libc_start_files was empty, just migrate the content of the former into
the latter.

libc-glibc: remove 2.3.6

This is an obsolete version which is no longer used by any sample (the only
user, the ia64 sample, has been removed).

It also makes the code path a bit complex, with twists just to accomodate
that version. Removing the version will make those twists go away, and
will ease commonalisation of glibc and eglibc in the future (hopefully!).

arch: remove ia64

ia64 is broken in every gcc/glibc combinations I tested (except for the

Nobody complained on the list about not being able to build recent versions.

So the only way forward I can see is to remove the architecture altogether.
