A bunch of TLS test in gcc testsuite [1] fails on alphaev68-linux-gnu with:

~/gcc-build/gcc/xgcc -B ~/gcc-build/gcc/ -O2 -flto run-ie.c
/usr/lib/gcc/alpha-unknown-linux-gnu/4.4.5/../../../../alpha-unknown-linux-gnu/bin/ld:

int main (void)

Attached are two mentioned files from the -save-temps compilation. I can
provide more information on request.
