com32: Use --as-needed for LDFLAGS
This extends commit 4678fd92a21e ("elflink: fix dependency problem in
cmenu/Makefile") and basically reverts commit fb543aa635ff ("com32:
Per-object file LDFLAGS"). By using the --as-needed ld argument we can
specify all the required shared libraries for a directory, even if not
all of the libraries are needed by every .c32 file. --as-needed takes
care of only creating DT_NEEDED entries for the shared libraries that
are actually required to resolve undefined symbols in a given module.
Furthermore, by using $(LIBS) we create a dependency between .c32
files and their shared libraries, which allows multiple make jobs to
run in parallel.
