Pass -Wl,-no_fixup_chains to ld64 when appropiate
Recent versions of MacOS use a version of ld where `-fixup_chains` is on by default.
This is incompatible with our usage of `-undefined dynamic_lookup`. Therefore we
explicitly disable `fixup-chains` by passing `-no_fixup_chains` to the linker on
darwin. This results in a warning of the form:
ld: warning: -undefined dynamic_lookup may not work with chained fixups
The manual explains the incompatible nature of these two flags:
-undefined treatment
Specifies how undefined symbols are to be treated. Options are: error, warning,
suppress, or dynamic_lookup. The default is error. Note: dynamic_lookup that
depends on lazy binding will not work with chained fixups.
