[PATCH v2] new option: object-shortname

[Thomas Martitz]

This option is intended to be used in conjunction with subdir-objects and
Automake-time substitutions for included makefile fragments (%C%, %D%).
Enabling the option shortens the file name of object files such that the 
prefix
derived (after canonicalization) from the path is not included.

Enabling the option is basically equivalent to setting foo_SHORTNAME =
foo. However, it also works flawlessly if a Makefile fragment is
conditionally included. Note that actually setting foo_SHORTNAME
still overrides the object name, regardless of this option. This can improve
the modularity of Automake-using projects.

Example:
without object-shortname
  sub/Makefile.am:
  bin_PROGRAMS += %D%/foo
  %C%_foo_CFLAGS = $(AM_CFLAGS) -g

results in objects:
  sub/sub_foo-foo.o

with object-shortname the object file name is:
  sub/foo-foo.o

And it allows the following in $(top_srcdir)/Makefile.am (not possible 
with foo_SHORTNAME=f
  if ENABLE_SUB
  include sub/Makefile.am
  endif
