    [gdb/contrib] Handle STRIP_ARGS_{STRIP,KEEP}_DEBUG in cc-with-tweaks.sh
    
    Handle new environment variable STRIP_ARGS_STRIP_DEBUG, defaulting to
    --strip-debug in gdb/contrib/cc-with-tweaks.sh, such that we can easily
    reproduce the PR29277 assert using:
    ...
    $ export STRIP_ARGS_STRIP_DEBUG=--strip-all
    $ make check RUNTESTFLAGS="gdb.base/jit-reader.exp \
        --target_board cc-with-gnu-debuglink"
    ...
    
    For completeness sake and to avoid confusion about which of the two used strip
    invocations the passed args apply to, likewise add STRIP_ARGS_KEEP_DEBUG,
    defaulting to --only-keep-debug.
    
    Script checked with shellcheck, no new warnings added.
    
    Tested on x86_64-linux.
