On x86-64/Linux I get:

ERROR: configure test passed without -Werror but failed with -Werror.
       This is probably a bug in the configure script. The failing command
       will be at the bottom of config.log.
       You can run configure with --disable-werror to bypass this check.

Makefile:73: recipe for target 'config-host.mak' failed

and the last part of config.log is

    ccache compiler [compiler options]
    compiler [compiler options]          (via symbolic link)

Options:
    -c, --cleanup         delete old files and recalculate size counters
                          (normally not needed as this is done automatically)
    -C, --clear           clear the cache completely (except configuration)
    -F, --max-files=N     set maximum number of files in cache to N (use 0 for
                          no limit)
    -M, --max-size=SIZE   set maximum size of cache to SIZE (use 0 for no
                          limit); available suffixes: k, M, G, T (decimal) and
                          Ki, Mi, Gi, Ti (binary); default suffix: G
    -o, --set-config=K=V  set configuration key K to value V
    -p, --print-config    print current configuration options
    -s, --show-stats      show statistics summary
    -z, --zero-stats      zero statistics counters

    -h, --help            print this help text
    -V, --version         print version and copyright information

The configure options for this build are
'--cc=ccache gcc' '--enable-debug' '--python=python3'

Looks like something is mishandling CC.

On FreeBSD I get an odd linker error:

  LINK    qemu-ga
/usr/bin/ld: cannot open linker script file ../config-host.ld: No such
file or directory
c++: error: linker command failed with exit code 1 (use -v to see invocation)
gmake: *** [Makefile:688: qemu-ga] Error 1
