Could you please provide the complete failing command line? Thanks.

No, EXTRA_HEADERS has to remain in gcc until the target headers are
moved to either libgcc or their own toplevel directory. They are
supposed to be installed into gcc/include during the build (and before
building libgcc is attempted), and should be findable from there.
That's why I'm asking for the complete command line to see where gcc is
looking for headers.
