Subject: [PATCH 06/13] perf tools: include basename for non-glibc systems

perf uses the glibc version of basename(), by defining
_GNU_SOURCE, including string.h and not including libgen.h.
The glibc version of basename is better than the POSIX
version since it does not modify its argument.

Android has only one version of basename which is defined in
libgen.h. This version is the same as the glibc version.

Error on Android:
util/annotate.c: In function 'symbol__annotate_printf':
util/annotate.c:503:3: error: implicit declaration of function 'basename'
[-Werror=implicit-function-declaration]
util/annotate.c:503:3: error: nested extern declaration of 'basename'
[-Werror=nested-externs]
util/annotate.c:503:14: error: assignment makes pointer from integer without
a cast [-Werror]

On Android libgen.h should be included to define basename.
