build-system: fix libdivecomputer build on macOS

Browse source 
In some Mac environments autotools somehow think that we have clock_gettime(),
even though it isn't supported. Somehow the previous workaround stopped working
as make ended up re-running ../configure and overwriting our change. This tries
to work around that problem.
