Subject: LD_PRELOAD should treat space and colon as separator

from reading the code in dynlink.c, load_preload(), it appears as if 
musl's LD_PRELOAD only accepts space as a separator.

according to http://man7.org/linux/man-pages/man8/ld.so.8.html
GLIBC and probably other dynlinker accept ":" as well:

LD_PRELOAD
         A list of additional, user-specified, ELF shared libraries to
         be loaded before all others.  The items of the list can be
         separated by spaces or colons.
