New libc version support

[Thomas Jourdan <tjourdan at neuf dot fr>]

Hi

This patch adds support for glibc 2.8 and 2.9, and eglibc 2.9. It
depends on the experimental feature. You can apply it against the
revision 1271.

I did not build workable toolchains yet with thoses libc versions. This
is for later.

Regards,
Thomas
