Upgrade to version 4.7.5 and take over maintainership from ports@.

There is something going on with optimizations on both the old and
new versions.

If you set USE_GCC=any the port will build way faster:

gcc:   make   506.90s user 17.86s system 228% cpu  3:49.41 total
clang: make  3913.28s user 23.73s system 211% cpu 31:05.70 total

I added a GCC option for now.

Setting CFLAGS to -O0 will make clang go as fast as gcc.
Explanation still unknown.
