+Subject: [PATCH] Set vapidir
+
+Use parentheses instead of braces, it makes automake and perl happy
+newer perl does not like ${} for VALAFLAGS
+
+Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.30), passed through in regex; marked by <-- HERE in m/^${ <-- HERE abs_top_builddir}/gsound$/ at TOPDIR/build/tmp/work/mips32r2-yoe-linux/gsound/1.0.2-r0/recipe-sysroot-native/usr/bin/automake line 5759.
