Khem Raj ea00dbbcf3 bitbake.conf: Switch prefix mapping to use -ffile-prefix-map
-ffile-prefix map is more comprehensive when it comes to reproducible
builds and its superset of all prefix-mapping options in compilers

This makes is cleaner and workable across gcc and clang, clang does not
support -fcanon-prefix-map and it has to be explicitly omitted when using
clang.

There are lambdas generated in templates by clang which still get the
absolute paths despite -fdebug-prefix-map, this helps with that as well.

nasm is an outlier and we have fixed it by adding -fdebug-prefix-map option
luckily we do not pass DEBUG_PREFIX_MAP to nasm, in all recipes which use
nasm either pass -fdebug-prefix-map explicitly to nasm or they rewrite it
to use nasm flags syntax.

We have discussed this in past [1]
