Another sharp edge... You can use the proper linker flags to link to
the static archive rather than the shared object (like -l:libz.a*),
and it will work fine on Linux and Solaris. But Apple linkers will
still link to the shared object anyways. Even on iOS where shared
object runtime linking was forbidden.

In the Apple cases, I either (1) deleted the shared objects; or (2)
used sed to call out the archive.

[*] See the ld man page for -l:libz.a,

-l namespec
    Add the archive or object file specified by namespec to the list
    of files to link. This option may be used any number of times. If
    namespec is of the form :filename, ld will search the library path
    for a file called filename, otherwise it will search the library path
    for a file called libnamespec.a.
