-----------------------------------+----------------------------------------
 If perl5.12 is built +universal, then sane-backends will fail to build
 unless it is also built universal.  This is because sane-backends queries
 perl to figure out what LDFLAGS to use.  These LDFLAGS will include '-arch
 i386 -arch x86_64' even though sane-backends is only being built for
 x86_64.

 This build failure will look like this to the user because libusb will not
 be universal:

 config.log shows the real cause:
