Hi,

i had compile util-linux-2.23 successfully, but when i test mount binary,

$ cd util-linux-2.23

$ cd .libs

$ ./mount

mount[5449]: segfault at 2f ip 00007f593a84f903 sp 00008fff894870e8 error 4 in libc.so[7f593a804000+72000]

Segmentation fault
$

util-linux-2.23 version use qsort_r(), so i added it from ccl (C Containers library)

and changed parameter order.

vi musl/include/stdlib.h

typedef int cmp_t(void *, const void*, const void*);

void qsort_r(void *, size_t, size_t, cmp_t *, void*);
