Clarify a workaround for older versions of LLD for MinGW (#6836) [skip ci]
The previous diagnosis (that the wrapper that injects the -target
option to clang caused the issues) doesn't seem right; the issue
was that LLD's MinGW frontend (which is invoked when ld.lld is given
a COFF argument to the -m option) didn't handle the --version argument
before LLD 9.0.0.
