When the debug-prefix-map and macro-prefix-map compiler flags
were change to file-prefix-map[1] the -fcanon-prefix-map
flag was removed, most likely accidentally.
Due to this the file paths were not canonicalized before
substituting them, so they did not always match the corresponding keys.
E.g. relative pathes were not converted to absolute ones:
../../sources/foo.cpp doesn't match ${S}/foo.cpp, and due to
this some debug sources were missed.
This patch adds back the -fcanon-prefix-map flag.
