ase (of the
cross-gcc) that=E2=80=99s failing.

In cross-base.scm (in master), one of them is like this:

                   (setenv "CROSS_CPATH"
                           (string-append libc "/include:"
                                          linux "/include"))

Could it be that in your case =E2=80=98linux=E2=80=99 above is #f, hence th=
e error?

HTH,
