The reason was that the invocation of the cpuid_tool through the makefile
was using LD_LIBRARY_PATH=. to force link&use of the latest-build libcpuid
library. This doesn't seem to work, so using LD_PRELOAD to explicitly load
libcpuid.so into cpuid_tool.
The committed approach of course doesn't work on Mac OS X, where
make test-old should be used.
The last change to flags detection caused a bunch of tests to fail.
The reason is that they are bogus, all recent Intel chips don't have
RDTSCP indicated in the test files, whereas they have it in reality.
I figured it will be easier to add "--fix" option to run_tests.py,
rather than fixing each testfile by hand.
This is also extended in the Makefile:
"make test" runs the tests and reports discrepancies.
"make fix-tests" fixes any offending tests. This blindly assumes that
libcpuid is sane.
cpuid_tool: the --load flag didn't have any effect with queries; fixed
tests: added a trivial testing framework, added 7 tests
