> Description:

	On NetBSD/sparc64, the boehm-gc build fauls with

libtool: compile:  gcc -DHAVE_CONFIG_H -I./include -I/var/obj/pkgsrc/devel/boehm-gc/work/.buildlink/include -fexceptions -Wall -Wextra -O2 -fno-strict-aliasing -MT fnlz_mlc.lo -MD -MP -MF .deps/fnlz_mlc.Tpo -c fnlz_mlc.c  -fPIC -DPIC -o .libs/fnlz_mlc.o
libtool: compile:  gcc -DHAVE_CONFIG_H -I./include -I/var/obj/pkgsrc/devel/boehm-gc/work/.buildlink/include -fexceptions -Wall -Wextra -O2 -fno-strict-aliasing -MT fnlz_mlc.lo -MD -MP -MF .deps/fnlz_mlc.Tpo -c fnlz_mlc.c -o fnlz_mlc.o >/dev/null 2>&1
gmake[1]: *** No rule to make target 'sparc_mach_dep.lo', needed by 'libgc.la'.  Stop.
gmake[1]: Leaving directory '/var/obj/pkgsrc/devel/boehm-gc/work/gc-7.4.2'
Makefile:1716: recipe for target 'all-recursive' failed
gmake: *** [all-recursive] Error 1
*** Error code 2

Stop.
make[2]: stopped in /usr/src/pkgsrc/devel/boehm-gc
*** Error code 1

	The related source file is at src/sparc_mach_dep.S; I guess
	autohell is missing something here.

	Detailed logs are at
	<https://www2.spg.tu-darmstadt.de/~hf/pkgsrc/boehm-gc-sparc64.tgz>


> How-To-Repeat:

	Build devel/boehm-gc on NetBSD/sparc64.

> Fix:
	Apply sufficient anounts of auto fu, I guess.

>Fix:
