Hi,

things still seem to be failing (
https://gdb-build.sergiodj.net/builders/Fedora-x86_64-cc-with-index/builds/12689/steps/test%20gdb/logs/stdio
):
...
make -k check 'RUNTESTFLAGS=CC_FOR_TARGET="/bin/sh
/home/gdb-buildbot/fedora-x86-64-3/fedora-x86-64-cc-with-index/binutils-gdb/gdb/contrib/cc-with-tweaks.sh
-i gcc" CXX_FOR_TARGET="/bin/sh
/home/gdb-buildbot/fedora-x86-64-3/fedora-x86-64-cc-with-index/binutils-gdb/gdb/contrib/cc-with-tweaks.sh
-i g++"' -j4 FORCE_PARALLEL=1 TS=1
   ...
make[1]: *** No rule to make target 'gcc CXX_FOR_TARGET=/bin/sh'.
make[1]: *** No rule to make target 'g++'.
...
?

Thanks,
