attempting to cross-compile glibc-2.3.6 for the hppa2.0 target fails with an
ICE when the host system is 64bit:
$ hppa2.0-unknown-linux-gnu-gcc -c seed48_r.i
seed48_r.i: In function 'main':
seed48_r.i:1: error: unrecognizable insn:

(expr_list:REG_EQUAL (const_int 25214903917 [0x5deece66d])
(nil)))
seed48_r.i:1: internal compiler error: in extract_insn, at recog.c:2084
