I adapted my code from security/gnupg:

options.mk: ----------------------------------------------------------------

.if ${MACHINE_ARCH:Mi386}
PKG_SUPPORTED_OPTIONS+= i586-optimized
.endif

:
:
:

.if !empty(PKG_OPTIONS:Mi586-optimized)
# use assembler routines optimized for, and only for!, i586
ONLY_FOR_PLATFORM=      *-*-i386
MACHINE_GNU_ARCH=       i586
.endif
----------------------------------------------------------------------------


I "PKG_SUPPORT" now in all cases. Further reviews and comments are welcome.

Best, Stefan Schaeckeler
