perf tools build in recent kernels spews splat when cross compiling with uClibc:
| CC util/alias.o
| In file included from tools/perf/util/../ui/../util/cache.h:8:0,
| from tools/perf/util/../ui/helpline.h:7,
| from tools/perf/util/debug.h:8,
| from arch/../util/cpumap.h:9,
| from arch/../util/env.h:5,
| from arch/common.h:4,
| from arch/common.c:3:
| tools/include/linux/string.h:12:15: warning: redundant redeclaration of ‘strlcpy’ [-Wredundant-decls]
| extern size_t strlcpy(char *dest, const char *src, size_t size);
^
This is after commit 61a6445e46 ("tools lib: Guard the strlcpy() header with
__GLIBC__").
The problem is uClibc also defines __GLIBC__ for exported headers for
applications. So add that specific check to not trip for uClibc.
