configure.cflags and -arch flags

[Ryan Schmidt]

I am curious if there is a good reason why variables like configure.cflags don't contain the -arch flags. During the standard configure phase, MacPorts does put the -arch flags into e.g. the CFLAGS environment variable, but if you use e.g. configure.cflags yourself to fix ports that don't use a standard configure phase, the -arch flags are missing, and must be handled separately, both for single-arch and universal cases. This kind of conditional code is tedious, and Toby thinks this didn't used to be required:
