tools build: Check basic headers for test-compile feature checker
An i386 binary can be linked correctly even without correct headers.
Which causes problem. For exmaple:
$ mv /tmp/oxygen_root/usr/include/gnu/stubs-32.h{,.bak}
$ make tools/perf
Auto-detecting system features:
... dwarf: [ on ]
[SNIP]
GEN common-cmds.h
CC perf-read-vdso32
In file included from /tmp/oxygen_root/usr/include/features.h:388:0,
from /tmp/oxygen_root/usr/include/stdio.h:27,
from perf-read-vdso.c:1:
/tmp/oxygen_root/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No
such file or directory
# include <gnu/stubs-32.h>
^
compilation terminated.
...
In this patch we checks not only compiler and linker, but also basic
headers in test-compile test case, make it fail on a platform
lacking correct headers.
