ok so you probably forgot to add libz to the -L path
and then ld went ahead and found the wrong one

this is ok
(in general you may also want to look at rpath too)

you probably have an /home/mudd/musl/etc/ld-musl-i386.path
that is visible to the first command but not to the second
(nor to ld).
you may also want to figure out why ld tried the system
paths (it either uses hard coded paths or gets them from
some ld.so.conf, you can figure out what it's doing by
using strace -f on the build command)
