tmpfs-backed WRKDIR is certainly possible with lang/gcc* ports, albeit
I'm not sure if 128MB is enough.  However, normally I never limit tmpfs
size, but try to provide sufficient swap space.

That said, I observed similar "no space left on device" errors even on
a box with 16GB of RAM when building lang/gcc *with default options*,
which includes JAVA.

I always patch all lang/gcc* ports locally like this:

  -OPTIONS_DEFAULT_i386=	JAVA
  -OPTIONS_DEFAULT_amd64=	JAVA
  +#OPTIONS_DEFAULT_i386=	JAVA
  +#OPTIONS_DEFAULT_amd64=	JAVA

It allows to use tmpfs-backed storage of sane sizes to build them.  I
once wondered why is JAVA in the defaults anyways; someone gave me the
reason, which I cannot remember right now.
