The problem is not that LTO is "very resource consuming". The problem is that
GCC mal-parallelized the build and it is spawning exceedingly many processes.
Such mal-parallelization is a pitfall of GNU Make. All one has to do is to use
-jN at multiple levels of the directory hierarchy and similar effect would be
achieved.
They should fix the bug first before others use this feature.
I am not sure why this buggy feature was enabled in the FreeBSD port in the
first place.
