We should make local PGO builds Just Work so that issues like bug 1341525 comment 24 don't happen.

Possibly this could be done by the compiler automatically (see also https://bugs.llvm.org/show_bug.cgi?id=40877 for --coverage).

This bit me today. :-(

Workaround from https://bugzilla.mozilla.org/show_bug.cgi?id=1341525#c25 is to include:

export LIB=$LIB;path\\to\\.mozbuild\\clang\\lib\\clang\\VERSION\\lib\\windows\\

in .mozconfig.
