Florian Weimer 562ef5e69e misc: Add internal __getauxval2 function 
The explicit error return value (without in-band signaling) avoids
complicated steps to detect errors based on whether errno has been
updated.

Aurelien Jarno 0b8dedd38f Add sys/auxv.h wrapper to include/sys/ 
The GNU libc testsuite fails to build on powerpc/ppc64/ppc64le with the
following error:

    ../sysdeps/powerpc/test-get_hwcap.c:26:22: fatal error: sys/auxv.h: No such file or director

This is because test-get_hwcap.c includes <sys/auxv.h>, but we don't
provide a wrapper in include/sys. This patch adds one.

Changelog:
	* include/sys/auxv.h: New file.
