Just so you know what the issue here is: When configure fails to find a
working install program it uses the install-sh that is shipped. It creates
an output variable like INSTALL=./config/install-sh. When it substitutes
this into the makefiles (@INSTALL@) it adjusts the paths so they have the
right number of `../'. In the current Postgres build this gets only
substituted into Makefile.global, therefore the relative paths are wrong
when it's included from another directory.

It's probably futile to argue whether the relative paths have a merit, the
only way to work around this is to substitute INSTALL into every makefile
where it's used, which is what I'm in the process of doing.

The current workaround is to write AC_CONFIG_AUX_DIR(`pwd`/config) which
will generate the absolute path. But this will create problems with
libtool, which statically scans configure.in for a place to put its
ltconfig.sh and related stuff. It doesn't know that `pwd` is not a
relative file name.

(There is also a related reason that you can't use
AC_OUTPUT($some_variable), because Automake needs to statically determine
all .in files that are touched.)
