[Fontconfig] [PATCH] doc: fix parallel build failure

[Mike Frysinger]

The sgml file generation needs a local edit-sgml helper, but doesn't
depend on it, so when you build in parallel, it could fail like so:
...
make[2]: Entering directory '.../fontconfig/doc'
ln -s fontconfig-devel.sgml local-fontconfig-devel.sgml
rm -f fcatomic.sgml
rm -f fcblanks.sgml
rm -f fccache.sgml
./edit-sgml ./func.sgml < 'fcatomic.fncs' > fcatomic.sgml
  CC     edit-sgml.o
./edit-sgml ./func.sgml < 'fccache.fncs' > fccache.sgml
./edit-sgml ./func.sgml < 'fcblanks.fncs' > fcblanks.sgml
/bin/sh: ./edit-sgml: No such file or directory
make[2]: *** [fcatomic.sgml] Error 127
make[2]: *** Waiting for unfinished jobs....
/bin/sh: ./edit-sgml: No such file or directory
/bin/sh: ./edit-sgml: No such file or directory
make[2]: *** [fccache.sgml] Error 127
make[2]: *** [fcblanks.sgml] Error 127
make[2]: Leaving directory '.../fontconfig/doc'
...
