[Bug bootstrap/15226] New: bootstrap failure in collect2.c: parse error before "FILHDR"

["dtucker at zip dot com dot au" <gcc-bugzilla at gcc dot gnu dot org>]

Bootstrapping on AIX 4.2.1 (yeah, I know it's old) fails because of some missing
declarations (FILHDR and SYMENT, they're in filehdr.h syms.h respectively).  I
got it to build by adding those includes to gcc/collect2.c (I'll attach the
trivial patch, it's probably not the right thing but it works for me).

$ /home/dtucker/gcc-3.4.0/configure --enable-languages=c --disable-nls
--with-included-gettext --enable-threads=aix && make bootstrap
