fix musl-gcc wrapper to be compatible with default-pie gcc toolchains

the specfile for the wrapper was written assuming output is pie only
if -pie appears on the command line. recent (and older patched)
versions of gcc can be configured to produce pie output by default,
adn when used with such a toolchain, the wrapper linked the wrong
startfiles (crt*) containing pic-incompatible code.

rather than trying to figure out gcc's default, simply always use the
pic-compatible start files.
