We don't need this for any functional purpose, but when debugging hosts
it is useful to know what binary a given capabilities XML document is
associated with.

Looks like "make syntax-check" is not happy about this if statement:
../src/qemu/qemu_capabilities.c:3904: if (!STREQ(str, qemuCaps->binary)) {
build-aux/syntax-check.mk: Use STRNEQ instead of !STREQ and STREQ instead of !STRNEQ

make: *** Waiting for unfinished jobs....

8.96 prohibit_canonicalize_without_use
This patch also broke 6 tests in 'make check', at least here in my env:
FAIL: domaincapstest
FAIL: qemuxml2argvtest
FAIL: qemuxml2xmltest
FAIL: qemublocktest
FAIL: qemusecuritytest
FAIL: qemucapabilitiestest
Thanks,
