[Bug other/13993] New: Relative path as srcdir causes problem

[Hilfinger at gnat dot com]

Configuring the head version of GCC with 

  CC=gcc ../../src/gcc-head/configure --enable-languages="c" \
--prefix=$HOME/obj/gcc-head/install

causes a problem after

make bootstrap
make install

Specifically, within the gcc subdirectory, 'make install' looks for install-sh
in ../../src/gcc-head, the top-level source directory, which is wrong (should be
../../../src/gcc-head.  This is a change from earlier versions (3.3.2, for
example).  It is causes by the definition of INSTALL in the top-level
Makefile.in, which gets passed down to and overrides the (correct) definition
of INSTALL in the gcc subdirectory.  

If the use of relative paths when invoking configure is to be deprecated, there
should be a warning.  Better still, revert to the previous definition of INSTALL
or otherwise convert to an absolute pathname for INSTALL, as previous versions
did.
