Comment (by birdie):

 Replying to [comment:4 cehoyos]:
 > If you really need faster build time, search for `LDFLAGS` in
 ffbuild/config.mak and change `-flto` to `-flto=4`. Not sure how easy this
 is to allow in configure.

 This sounds like a great idea - thanks but I still hope that Makefile
 could be altered, so that 'make -jN' also made linking with -flto faster
 by default.
