>Description:
security/gnupg has a build problem on sparc when you use any -mcpu 
optimization flag, as was already described in this thread: 
http://mail-index.netbsd.org/port-sparc/2004/12/19/0001.html 
>How-To-Repeat:
with CFLAGS=-pipe -mcpu=supersparc set in /etc/mk.conf, the build breaks: 

Making all in checks

I.e. the build completed but the post-build tests fail.  If you skip the
"checks" step, the binaries can be properly installed but show the same
error all the time.  

I haven't verified this problem (nor its fix) on sparc64 yet.  
>Fix:
This security/gnupg/hacks.mk solves the problem: 

# $NetBS$

.ifndef GNUPG_HACKS_MK
GNUPG_HACKS_MK=         #defined

### workaround for a GCC optimizer bug on sparc:
### drop any -mcpu flag
###
.if ${MACHINE_ARCH} == "sparc"
PKG_HACKS+=             mcpu
BUILDLINK_TRANSFORM+=   rm:-mcpu=.*
.endif

.endif
