This patch fixes a case where it find crypt defined in libc (musl) but
not in specified libraries then it ends up assigning
LIBCRYPT="-l" which then goes into makefile cause all sort of problems
e.g.
ld: cannot find -l-m32
| collect2: error: ld returned 1 exit status
The reason is that -l appears on commandline with out any library and
compiler treats the next argument as library name whatever it is.
