The auxtrace code needed by Intel PT uses the __get_cpuid() gcc builtin,
that is not present in old systems, breaking the build.
Add a test to check for that builtin and disable AUXTRACE in those
systems.
[acme@rhel5 linux]$ make NO_LIBPERL=1 -C tools/perf O=/tmp/build/perf install-bin
make: Entering directory `/home/acme/git/linux/tools/perf'
BUILD: Doing 'make -j2' parallel build
Auto-detecting system features:
<SNIP>
... lzma: [ on ]
... get_cpuid: [ OFF ]
<SNIP>
config/Makefile:630: Your gcc lacks the __get_cpuid() builtin, disables support for auxtrace/Intel PT, please install a newer gcc
MKDIR /tmp/build/perf/util/
<SNIP>
This fixes the build on old systems such as RHEL/CentOS 5.11.
