Alexandre Oliva 39ab2e4c39 libcody: fix nonportable shell code in revision.stamp build rule
Two non-portable shell constructs have been long present in libcody's
build rule for revision.stamp: $() instead of ``, and += to append to
a shell variable.  The former seems to work even when bash is
operating as /bin/sh, but += doesn't, and it ends up trying to run
revision+=M as a command name, and issuing an error as that command is
(hopefully) not found.

This patch replaces both constructs with more portable ones.


for  libcody/ChangeLog

	* Makefile.in (revision.stamp): Replace $() and += with more
	portable shell constructs.
