Oh, sorry for the missing explanation... in my case the reason was the
following:
For the OSX packages I build of pciutils and flashrom, I add "-arch i386
-arch x86_64" to the CFLAGS on the make command line in order to create
bi-arch binaries.
However, this does not work when creating dependency files, so the build
process failed very early. The patch separates compiler flags that
influence the preprocessor and those that influence code generation and
changes the compiler calls to combine the two accordingly where needed.
With the patch, flashrom will also recognize and enable libftdi and
libusb on OSX.
