Diffing against the last merge base, I see some accel-gcc mentions still
remain in the build system, which I assume can also be removed now?  That
is, accel_target_* stuff in Makefile.def and Makefile.tpl.

As we now no longer build accel-gcc, my commit r211513 ÂDifferent
configure and make flags for target vs. accelerator GCCÂ should be
reverted, too.

The Âaccelerator target system typeÂ check complains:

    $ ../source/configure --prefix=[...] --disable-bootstrap --enable-languages=c,c++,fortran,lto --disable-multilib [...]
    checking build system type... x86_64-unknown-linux-gnu
    checking host system type... x86_64-unknown-linux-gnu
    checking target system type... x86_64-unknown-linux-gnu
    checking for a BSD-compatible install... /usr/bin/install -c
    checking whether ln works... yes
    checking whether ln -s works... yes
    checking for a sed that does not truncate output... /bin/sed
    checking for gawk... gawk
    checking accelerator target system type... config.sub: missing argument
    Try `config.sub --help' for more information.
    
    checking for libatomic support... yes

I suspect this is due to:

... accel_target_noncanonical no longer being initialized here, but then
used in config/acx.m4:ACX_CANONICAL_ACCEL_TARGET.


GrÃÃe,
