Found during tests of busybox package:
If the path of the top build directory contains a symlink and the
project's build scripts normalize pathnames, no debug info is
created by cygport.
This is because options like
-fdebug-prefix-map=${B}=/usr/src/debug/${PF}
have no effect because ${B} contains a symlink but the compiler is
run with the real source path.

Sidenote: we should probably also be using file-prefix-map, now
we're on a gcc which supports it.
... also macro-prefix-map, although it looks like changing to
-ffile-prefix-map is equivalent to -f*-prefix-map which future proofs
the options!
So I updated to using -ffile-prefix-map in cygport 0.36.8, since that
seems like the "Right Thing(TM)"
I discovered today that, amazingly, this breaks compiling ruby, since in
one place it does:
#include __FILE__
(yeah, that's pretty jaw dropping...)
