[git commit] test: Fix math .c dependency

[Bernhard Reutner-Fischer]

commit: http://git.uclibc.org/uClibc/commit/?id=a20a91ad7c042c46e4a2adee6d03315f857f9985
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

When explicitly running the compile target we were missing a dependency
to generate the libm-test.c.
