[PATCH] configure: Simplify flag checks for Mac preloader.

[Brendan Shanks]

Always build the Mac preloader with '-mmacosx-version-min=10.7', which
works with all supported toolchains.
Fixes bug when building with Xcode 9 where preloader flags would be added
to EXTRACFLAGS and cause build failures on 32-bit.
