Problem building 3.4.3 on solaris 8

[Warren L Dodge <warrend at mdhost dot cse dot tek dot com>]

I am trying to build gcc-3.4.3 on solaris 8. I get to the make install point
and then there is a problem. It appears the INSTALL variable is not getting
set right for the install step in the various directories.

I have the source in ..../gcc-3.4.3 and the build dir is ..../gcc-3.4.3_sun5.8

Here is the first error. Notice the the gcc src tree is one level higher then
the install path is specifying.

make install
/bin/sh ../gcc-3.4.3/mkinstalldirs /proj/wdtprojects/wdt_tmp/gnu_sun5.8/gcc-3.4.3 /proj/wdtprojects/wdt_tmp/gnu_sun5.8/gcc-3.4.3

        true; \
else \
        echo timestamp > specs.ready; \
fi

  then \
    rm -f /proj/wdtprojects/wdt_tmp/gnu_sun5.8/gcc-3.4.3/bin/sparc-sun-solaris2.8-gnatbind; \
    ../gcc-3.4.3/install-sh -c gnatbind-cross /proj/wdtprojects/wdt_tmp/gnu_sun5.8/gcc-3.4.3/bin/sparc-sun-solaris2.8-gnatbind; \
    if [ -d /proj/wdtprojects/wdt_tmp/gnu_sun5.8/gcc-3.4.3/sparc-sun-solaris2.8/bin/. ] ; then \

Looking at the Makefile in ..../gcc-3.4.3_sun5.8/gcc it has 

INSTALL = ../../gcc-3.4.3/gcc/../install-sh -c

which is correct. So I assume that the INSTALL variable is being overwritten
from the main Makefile.

If you need more information let me know.
