I totally missed that %-}

With -static, cc fails nicely:

    $ cc -std=gnu99 -Wall -m64 -mcx16 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 
-D_LARGEFILE_SOURCE -Wstrict-prototypes -Wredundant-decls -Wundef 
-Wwrite-strings -Wmissing-prototypes -fno-strict-aliasing -fno-common -fwrapv 
-o config-temp/qemu-conf.exe config-temp/qemu-conf.c -m64 -static
    /usr/bin/ld: cannot find -lc
    collect2: error: ld returned 1 exit status

Good.  Next test: I install glibc-static and uninstall glib2-static.

    $ ./config.status 

    ERROR: sizeof(size_t) doesn't match GLIB_SIZEOF_SIZE_T.
           You probably need to set PKG_CONFIG_LIBDIR
           to point to the right pkg-config files for your
           build target
