libatomic multilib testing

[Steve Ellcey]

I was wondering if anyone else is seeing problems running the libatomic
testsuite with a multilib target?  It seems to have started failing for
me over the weekend but I can't seem to find any changes that would have
caused this.

I am running using the qemu simulator, and it works fine for the GCC and
libstdc++ testing but with libatomic I see:

spawn /mips/arch/overflow/codesourcery/mips-linux-gnu/pro/release/2012.03-67/Linux/bin/mips-linux-gnu-qemu -r 2.6.38 ./atomic-compare-exchange-1.exe
./atomic-compare-exchange-1.exe: error while loading shared libraries: libpthread.so.0: cannot open shared object file: No such file or directory
FAIL: libatomic.c/atomic-compare-exchange-1.c execution test

Additionally, when the testing is finished I exit with a 'Error 2', but I
think most testing, even when there are problems, should exit with '0'.

make[2]: Leaving directory `/local/home/sellcey/gcc/libatomic/obj-mips-mti-linux-gnu/gcc/final/mips-mti-linux-gnu/libatomic'
make[1]: *** [check-recursive] Error 1
