[PATCH] D53015: [LLD] [MinGW] Pass libpath to the COFF linker

[Martin Storsjö via Phabricator via llvm-commits]

mstorsjo created this revision.
mstorsjo added reviewers: rnk, smeenai, ruiu.

This is necessary for handling defaultlib directives embedded in object files, unless they use an absolute path.

This is needed in all incarnations of https://reviews.llvm.org/D53012 and regardless of whether https://reviews.llvm.org/D53013 is picked or not.
