sections, but the current code misses certain variants. In particular, those
named when clang takes the code path in
clang/lib/Driver/ToolChain.cpp:416, where crtfiles are named:
clang_rt.<component>-<arch>-<env>.<suffix>
Previously, the code only handled:
clang_rt.<component>.<suffix>
<component>.<suffix>
This revision fixes that.
