* implicit.c (pattern_search): After second expansion be sure to
handle order-only markers inside the expansion properly.
Fixes Savannah bug #31155.
* guile.c (guile_define_module): Technically a void* cannot
contain a pointer-to-function and some compilers warn about this.
Cast the function pointers.

* scripts/features/se_implicit: Verify that order-only tokens
inside second expansion are parsed correctly.
Test for Savannah bug #31155.
* run_make_tests.pl (set_more_defaults): If we can't find
gnumake.h based on the make program we might be running from a
remote build directory. Parse the Makefile for the right path.
