{{{SAGE_CHECK=yes}}} also works.

It also hangs with {{{CFLAGS=-O0}}}, and also if I do
{{{
.../pari-2.4.3.svn-12577.p5/src$ ./Configure --graphic=none --kernel=gmp
--tune
}}}
(which uses the system's GMP, which is version 4.3.1), regardless of
{{{CFLAGS}}} settings. (gcc is version 4.4.4.)
It doesn't always hang at ''exactly'' the same point (of output), but this
might simply be due to unflushed buffers; the point where it "stops" only
differs by some lines (different size / threshold for the same function,
when attempting to tune {{{REMIIMUL_LIMIT}}} if I understand correctly).
When I interrupt the tuning from within a Sage build with Control-C, I get
cores dumped. Plain PARI seems to catch the signal (properly) and exits
with
{{{
^C *** user interrupt.
*** Error in the PARI system. End of program.
}}}
but continues compilation (which of course fails).
