[Qemu-devel] [PATCH] Makefile: Remove qemu-version.h and qemu-options.def during 'make distclean'

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

qemu-version.h and qemu-options.def are generated files
that should be deleted during 'make distclean'.

This solves building issues with out-of-tree builds from
a source tree that has been built in (see d1bd2423a90).

This solves:

- /qemu-version.h existing in source tree:

    /source/qemu/qemu-nbd.c: In function ‘version’:
    /source/qemu/qemu-nbd.c:133:6: error: expected ‘)’ before
    ‘QEMU_FULL_VERSION’
     "%s " QEMU_FULL_VERSION "\n"
          ^~~~~~~~~~~~~~~~~~
          )
    /source/qemu/qemu-nbd.c:133:3: error: format ‘%s’ expects a matching
    ‘char *’ argument [-Werror=format=]
     "%s " QEMU_FULL_VERSION "\n"
      ~^
    cc1: all warnings being treated as errors

- /qemu-options.def existing in source tree:

    /source/qemu/vl.c: In function ‘main’:
    /source/qemu/vl.c:3052:18: error: ‘QEMU_OPTION_blockdev’ undeclared
    (first use in this function); did you mean ‘QEMU_OPTION_clock’?
                 case QEMU_OPTION_blockdev:
                      ^~~~~~~~~~~~~~~~~~~~
                      QEMU_OPTION_clock
    /source/qemu/vl.c:3052:18: note: each undeclared identifier is reported
    only once for each function it appears in
