[sparc64] Fix build of archivers/snappy

snappy 1.1.9 explodes horribly on sparc64:

/usr/obj/ports/snappy-1.1.9/bin/c++ -DHAVE_CONFIG_H -Dsnappy_EXPORTS -I. -I/usr/obj/ports/snappy-1.1.9/snappy-1.1.9 -O2 -pipe -Wall -Wextra -fno-exceptions -fno-rtti -DNDEBUG -fPIC -std=c++11 -MD -MT CMakeFiles/snappy.dir/snappy.cc.o -MF CMakeFiles/snappy.dir/snappy.cc.o.d -o CMakeFiles/snappy.dir/snappy.cc.o -c /usr/obj/ports/snappy-1.1.9/snappy-1.1.9/snappy.cc

size_t tag_type = AdvanceToNextTag(&ip, &tag);

...

There's a bit more.

This patch makes it _not_ set always_inline on sparc64. This fixes the build.

ok?
