I also experienced such a strange failure with -j2 on my uniprocessor Ath=
lon.
The problem was the glafp-utils/mkdependC/mkdependC script that is genera=
ted=20
during the build. The build gave a seemingly senseless error message so I=

looked at the script. Appearently, to concurrent make processes had tried=
 to=20
assemble it simultaneously, generating a pretty twisted version.
