[Qemu-devel] [PATCH] qapi: Fix compilation failure on sparc

[Eric Blake <eblake@redhat.com>]

Commit 86f4b687 broke compilation on sparc, which has a preprocessor
pollution of '#define sparc 1'.  Treat it the same way as we do for
the pollution with 'unix', so that QMP remains backwards compatible
and only the C code needs to use the alternative 'q_sparc' spelling.

Done as a followup to the same style of patch for MIPS; or we could
squash this into one patch.
