Build log is e.g. here:
https://buildd.debian.org/status/fetch.php?pkg=gnutls28&arch=amd64&ver=3.2.4-3&stamp=1378651617
https://buildd.debian.org/status/fetch.php?pkg=gnutls28&arch=powerpc&ver=3.2.4-3&stamp=1378653753

Can you really not reproduce this with

make -j8 && make -j8 check ?

FWIW in Debian I have worked around this by adding .NOTPARALLEL: to
guile/{,*}/Makefile*
