My diff had an extra "pwd" in arch/macppc/stand/ofwboot/Makefile;
I deleted the "pwd" before committing it.

>From my experiments with lld 10, I believe that macppc is almost ready
to switch from ld.bfd to ld.lld. I know of 2 other problems:
1. ports/lang/gcc/8 needs USE_LLD = No, because lld 10 can't link
C++ code from gcc. (I have not yet checked lld 11.) lld had no
problem with Fortran ports built by gcc.
2. All instances of -Wl,-relax or -Wl,--relax in src or ports must
be deleted, because it is an unknown option to lld, but lld can
link large binaries without the option.
