lang/gcc5-aux build hangs on amd64, no reference to PCH

["Thomas Mueller" <mueller6725%twc.com@localhost>]

from maya%netbsd.org@localhost:

> I've not made the same change to gcc*-aux packages.
 
> I've adjusted the gcc*-aux packages not to try to test for PCH support,
> so it will not hang now.
> I forgot I had ASLR disabled for other reasons so did not run into the

Now for some strange reason, building lang/gcc5-aux on NetBSD-8.99.1 amd64 hangs but no reference to PCH.

I ran a second attempt, with "make clean" before the second attempt.

Last two (long) lines of the build log were (first time)

Second time looks identical to the first.

I have an old build from NetBSD-7.99.15 amd64 of gcc-aux (gcc 4.9.2), from May 2015, may try to use that rather than fail at rebuilding for gcc-4.9.2.

Otherwise, I will try to build on FreeBSD. 

FreeBSD ports has lang/gcc5-aux and lang/gcc6-aux, no more gcc4-aux.

I had to go to Wikipedia for ASLR (too many acronyms for me to keep track of).  How do I disable ASLR on NetBSD, and can I disable ASLR for just one session?
