#58040: wxWidgets-3.2: builds on 10.7 but requires `--with-macosx-sdk` set to 10.8

 According to the official website, wxWidgets-3.2 will run on 10.7+, but
 when building on 10.7, it fails due to 10.8 - specific SDK features (log
 attached).

 Passing in the path to the 10.8 SDK on 10.7 does fix the build.

 I thought ${developer_dir}/SDKS/MacOSX10.8.sdk should be the path, but it
 turns out that is not correct on 10.7 at least. The following worked:
 {{{
 --with-macosx-
 sdk=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk
 \
 --with-macosx-version-min=${macosx_deployment_target} \
 }}}
