We currently pass $(KLIBCCPPFLAGS) to makeerrlist.pl, which is not expanded, so in an out-of-tree buld it only looks in the object directories and does not find linux/errno.h.

...Hutchings <ben at decadent.org.uk> CommitDate: Fri, 18 Jan 2019 03:10:14 +0000 [klibc] alpha: Support building without glibc headers Unless we use the "-nostdinc" option, gcc will implicitly include <bits/stdc-predef.h>, which is usually provided by glibc. This is part of $(KLIBCCPPFLAGS) which we generally include in compiler command lines. Add it to alpha's special rules for compiling the division subroutines.
