cmd/link: ensure cgo cflags do not leak into dwarf tests
Running the dwarf tests with CGO_CFLAGS set
with certain values would cause the test to fail. all.bash
would fail when CGO_CFLAGS was set to '-mmacosx-version-min=10.10'
because the --macosx-version-min flag is incompatible with some dwarf
tests. The change guards against using an unintended flag in the unit test.
