Commit ea4054a2 (modpost: handle huge numbers of modules) added
support for building a large number of modules.

Unfortunately, the commit changed the semantics of the makefile: Instead of
passing only existing object files to modpost, make now passes all expected
object files. If make was started with option -i, this results in a modpost
error if a single file failed to build.

Example with the current btrfs build falure on m68k:

fs/btrfs/btrfs.o: No such file or directory
make[1]: [__modpost] Error 1 (ignored)

This error is followed by lots of errors such as:

m68k-linux-gcc: error: arch/m68k/emu/nfcon.mod.c: No such file or directory
m68k-linux-gcc: fatal error: no input files
compilation terminated.
make[1]: [arch/m68k/emu/nfcon.mod.o] Error 1 (ignored)

This doesn't matter much for normal builds, but it is annoying for builds
started with "make -i" due to the large number of secondary errors.
Those errors unnececessari...
