Subject: [PATCH] Support POSIX basename() from musl libc
Musl libc 1.2.5 removed the definition of the basename() function from
string.h and only provides it in libgen.h as the POSIX standard
defines it.
This change fixes compilation with musl libc 1.2.5.

basename() modifies the input string, copy it first with strdup(), If
strdup() returns NULL the code will handle it.
