Where does binutils testsuite get CC?

[Dan Kegel]

Dear Miss Dejagnu,

The binutils testsuite refers to CC all over the place, e.g.
./ld/testsuite/ld-undefined/undefined.exp:if ![ld_compile "$CC -g" 
$srcdir/$subdir/undefined.c tmpdir/undefined.o] {

which fails for me.  My board file looks like this:

load_generic_config "unix";
set_board_info hostname ppc-405-linux-gnu
set_board_info username root-jail
set_board_info compiler 
/opt/cegl-2.0/ppc-405-linux-gnu/gcc-3.3-glibc-2.2.5/bin/ppc-405-linux-gnu-gcc
set_board_info c++compiler 
/opt/cegl-2.0/ppc-405-linux-gnu/gcc-3.3-glibc-2.2.5/bin/ppc-405-linux-gnu-g++

and I'm running dejagnu-1.4.3.  Should I also set CC and CXX in my board file?

Signed,
