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.
