cross-compiling from osx-64 to osx-arm64 can lead to badly linked libraries

[erykoff]

This is a follow-up to #589 which was not fixed correctly by #622

The issue is that in cross-compiling skip_test is marked as TRUE here

scikit-build/skbuild/resources/cmake/targetLinkLibrariesWithDynamicLookup.cmake

Lines 500 to 502 in f4f9796

	if(CMAKE_CROSSCOMPILING AND NOT CMAKE_CROSSCOMPILING_EMULATOR)
	set(skip_test TRUE)
	endif()

which short-circuits here

scikit-build/skbuild/resources/cmake/targetLinkLibrariesWithDynamicLookup.cmake

Lines 504 to 506 in f4f9796

	if(skip_test)
	set(has_dynamic_lookup FALSE)
	set(link_flags)

and therefore @isuruf's patch https://github.com/scikit-build/scikit-build/blob/main/skbuild/resources/cmake/targetLinkLibrariesWithDynamicLookup.cmake#L411-L413 is never triggered.

Not sure of the best way to work around this...
