Ok so that's exactly what I was thinking about: xxx-uclibc vs xxx-glibc.

See what happens for "arc-oe-linux-gnu":
--------------------------->8----------------------------
# ./mkheader linux-gnu arc-oe-linux-gnu  ../../libgpg-error-1.32/src/gpg-error.h.in ../config.h 1.33-unknown 0x012100 > /dev/null
../../libgpg-error-1.32/src/gpg-error.h.in:491: error including `../../libgpg-error-1.32/src/syscfg/lock-obj-pub.linux-gnu.h': No such file or
directory
--------------------------->8----------------------------

...and for "arc-oe-linux-uclibc":
--------------------------->8----------------------------
# ./mkheader linux-gnu arc-oe-linux-uclibc  ../../libgpg-error-1.32/src/gpg-error.h.in ../config.h 1.33-unknown 0x012100 > /dev/null
../../libgpg-error-1.32/src/gpg-error.h.in:491: note: including '../../libgpg-error-1.32/src/syscfg/lock-obj-pub.i686-unknown-linux-gnu.h'
--------------------------->8----------------------------

Any thoughts how "gnu" case should be handled?
