 Looks like the wrong compiler is being used; I expect the relevant errors
 are these:

 {{{

 There are also several errors messages which I expect are part of normal
 operation; Most of those are of this form:

 {{{
 /usr/bin/clang -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE
 -Wstrict-prototypes -Wredundant-decls -Wall -Wundef -Wwrite-strings
 -Wmissing-prototypes -fno-strict-aliasing -fno-common -fwrapv -c -o c
 onfig-temp/qemu-conf.o config-temp/qemu-conf.c
 config-temp/qemu-conf.c:2:2: error: __linux__ not defined
 #error __linux__ not defined
 }}}

 And one is different:

 {{{
 /usr/bin/clang -m64 -mcx16 -DOS_OBJECT_USE_OBJC=0 -D_GNU_SOURCE
 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -Wstrict-prototypes
