#67984: qemu configure does not recognize gcc as a valid objc compiler
--------------------------+----------------------
 Reporter:  barracuda156  |      Owner:  raimue
     Type:  defect        |     Status:  assigned
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.8.1
 Keywords:  powerpc       |       Port:  qemu
--------------------------+----------------------
 When I try building `qemu`, I get the following configure error:
 {{{
 ../qemu-8.0.4/meson.build:3420:13: ERROR: No host machine compiler for
 'audio/coreaudio.m'
 }}}

 I tried to disable `coreaudio` altogether, passing `--disable-coreaudio`,
 but then it fails a step further with:
 {{{
 ../qemu-8.0.4/meson.build:3810:58: ERROR: Tried to access compiler for
 language "objc", not specified for host machine.
 }}}

 Because Meson script coerces Obj C on Darwin:
 {{{
 if targetos == 'darwin'
   summary_info += {'Objective-C compiler': '
 '.join(meson.get_compiler('objc').cmd_array())}
 endif
 }}}
 Which is probably a bug (if no Cocoa and no Coreaudio, why ObjC?), but
 regardless of that, why GCC is not acknowledged in the first place?

 Macports does pass `--objcc=/opt/local/bin/gcc-mp-12`.
