Incomplete dependencies for libio/old*.c

[Andreas Schwab <schwab at suse dot de>]

Dependencies are generated using the non-pic command line (ie. without
-DSHARED).  This is a problem with some of the compatibility sources
which check SHLIB_COMPAT before including the headers, so that the
generated dependency list is incomplete.

	* Makeconfig (+mkdep): Add -DMAKING_DEPENDENCIES.
	* include/shlib-compat.h (SHLIB_COMPAT) [MAKING_DEPENDENCIES]:
	Define to 1.
