Bug#640547: /usr/bin/ld: cannot find -lgcc_s

[Peter Eisentraut]

Package: clang
Version: 2.9-10
Severity: important

Linking seems completely broken:

$ cat test.c
int main() { return 0; }
$ clang test.c
/usr/bin/ld: cannot find -lgcc_s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

In case it helps:

$ clang -v test.c

It still worked a few days ago, so it might be a transient mismatch
with the GNU toolchain.
