    tools lib: Reinstate strlcpy() header guard with __UCLIBC__ · 0215d59b

    perf tools build in recent kernels spews splat when cross compiling with uClibc:

    | 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 61a6445e ("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.
