Thanks Volodya, I'll give that a try.

Reading the sparc gcc manual it sounds like it might be the
combination of -m32 and -mcpu=v7 that is causing problems. The section
containing -m32 has the following written:
"These ‘-m’ options are supported in addition to the above on SPARC-V9
processors in 64-bit environments"

This seems to indicate that -m32 is only valid alongside v9.
