support for GNU/FreeBSD

support for GNU/FreeBSD

[Bruno Haible]

Hi,

Some people are working on a system with glibc and FreeBSD kernel. This
system has been assigned the canonical target name i486-pc-freebsd[4.X]-gnu.

Here is a patch to add support for this system. On one hand, it uses
te-freebsd.h so that the assembler can be used for the FreeBSD kernel.
On the other hand, it defines _GNU_SOURCE, as usually recommended on
Linux.

Note that the first patch (below) needs to add support only for the
i386 version of FreeBSD; the alpha version of FreeBSD does not need
modifications to gas/configure.in.

This shouldn't be needed.  The catch all:

    *-*-freebsd*)         fmt=elf em=freebsd bfd_gas=yes ;;

(line 991, rev 1.109) should work for "i386-*-freebsd*-gnu*" also.

It *is* needed because the catch-all line

      i386-*-gnu*)          fmt=elf ;;

comes earlier and therefore takes precedence over the line that you
mention.
