[Bug testsuite/38820] New: [4.2/4.3/4.4 Regression] During "make -i check" we set GCC_EXEC_PREFIX="/usr/local/lib/gcc/"

["rob1weld at aol dot com" <gcc-bugzilla at gcc dot gnu dot org>]

+++ This bug was initially created as a clone of Bug #14435 +++

I built "gcc version 4.4.0 20090111 [trunk revision 143259]" and when I
run "make -i check" it sets 'GCC_EXEC_PREFIX="/usr/local/lib/gcc/"'.


It seems gcc may look for this directory:

If you do NOT run "make install" _PRIOR_ to running "make -i check" then
how can we be thinking that "/usr/local/lib/gcc/" contains the _correct_
code to be used for the Testsuite ?

We should either require installation prior to checking (which is not
good but I do it to ensure I don't get hit) _or_ have "make -i check" do
a _partial_ installation to a temp directory and set the "GCC_EXEC_PREFIX"
environment variable to the temporary directory instead (preferred).

We need "GCC_EXEC_PREFIX" set to the code that was just compiled and not
to code that might have been installed weeks / months previously (or not
installed at all).
