[Bug ada/24468] New: link failure for several acats tests

["r dot emrich at de dot tecosim dot com" <gcc-bugzilla at gcc dot gnu dot org>]

A bunch of failed acats tests for gcc-4.0.2 using gnu as and gnu ld from
binutils-2.16.1, see:
http://gcc.gnu.org/ml/gcc-testresults/2005-10/msg00531.html

acats.log shows for example:
splitting

FAIL:   a83a02b 

Further analysis shows that the installed compiler gives a different picture:

$ gnatmake -g -I../../../support/ a87b59a.adb
gnatbind -aO./ -I../../../support/ -I- -x a83a02b.ali
gnatlink a83a02b.ali -g
/usr/lib/../lib32/libpthread.so: undefined reference to `_mpi_sgi_init'
collect2: ld returned 1 exit status
gnatlink: cannot call
/disk1/SCRATCH/gcc-build/IRIX64/mips-sgi-irix6.5/install/bin/gcc
gnatmake: *** link failed.

Same thing for at least a85013b and a87b59a.

This seems to be a problem with gnu ld 2.16.1. See:
