This machine has the 2014Q4 version of the ports tree.

After a few Google searches, I haven't noticed that this is a common/known problem so I guess there might be something peculiar about my system or the way I am doing things. Any ideas?
 
Is this on a real machine or in a VM?

It's a real machine. I fetched the latest 10/stable source and did a rebuild{world,kernel}:
Code:
FreeBSD 10.1-STABLE #0 r275002: Tue Nov 25 09:52:43 EST 2014
    hanzer@insomnia.bohemia.net:/usr/obj/usr/src/sys/INSOMNIA i386
FreeBSD clang version 3.4.1 (tags/RELEASE_34/dot1-final 208032) 20140512
The gcc build behavior hasn't changed. I've also noticed something odd about lang/go:
Code:
===>   Registering installation for go-1.3.2,1
pkg-static: (go-1.3.2,1) /usr/ports/lang/go/work/stage//usr/local/go/src/pkg/debug/elf/testdata/gcc-386-freebsd-exec - required shared library libc.so.6 not found
I don't know if it is related (other than being part of a suite of strange behavior from this box).
 
That's no issue. Do make rmconfig (it restores the defaults) or take a look to freshports http://www.freshports.org/lang/gcc48/

The default configuration options for lang/gcc on the 10.1_RELEASE ports collection has BOOTSTRAP set to off. So in a fresh installation, if one were to try to build a port that has lang/gcc as a dependency (say, editors/emacs-nox11) with make -DBATCH install clean, it will fail.

Granted, this is a minor issue once the solution is known - make config and set BOOTSTRAP=on for lang/gcc - but it did cost me a couple of days.
