I have the same problem in mk/tools/tools.SunOS.mk with Solaris10
and here is what i do
.if exists(/usr/bin/gzip)
TOOLS_PLATFORM.gunzip?=         /usr/bin/gunzip -f
TOOLS_PLATFORM.gzcat?=          /usr/bin/gzcat
TOOLS_PLATFORM.gzip?=           /usr/bin/gzip -nf ${GZIP}
#TOOLS_PLATFORM.gunzip?=                /usr/bin/gzip -df
#TOOLS_PLATFORM.gzcat?=         /usr/bin/gzip -cd
#TOOLS_PLATFORM.gzip?=          /usr/bin/gzip -nf ${GZIP}
.endif
