RFH: SIGBUS in buildd but not in porterbox

The package liblo runs a test suite at build time. This test suite
failed in mipsel (but not mips)[1]. I tried to reproduce the issue in
eder.d.o but it passed.

Liblo does use unaligned access (liblo had to be removed from sparc
for this reason).
But I'm confused as to why does the buildd error out and the porterbox
doesn't. Is it possible to (programatically) instruct the kernel to
not raise a SIGBUS?
