Note that we're now slightly inconsistent on wording for warnings about
missing modules:
./V01zmodload.ztst: starting.
Warning: zsh/example not linked: not checking autoloading
./V01zmodload.ztst: all tests successful.
./Y01completion.ztst: starting.
./Y01completion.ztst: skipped (the zsh/zpty module is not available)

though I appreciate that in V01, it is only some tests being skipped.

With gcc, dynamic modules were being disabled. Hence, it couldn't load
the modules. The problem was it was trying to use the linker options from
the native compiler. With the patch below, gcc now builds a dynamic zsh.

__SVR4 is not defined. configure finds /dev/ptmx and deems it usable.
sys/stropts.h also found and deemed usable. Cutting off the two
`&& defined(__SVR4)' sections doesn't help. What else might I try?
