syslinux-native: fix parallel building issue

There might be an error when parallel build:

[snip]
cp: cannot create directory `tmp/sysroots/x86_64-linux/usr/share/
syslinux/com32/include/gplinclude': No such file or directory
make[4]: *** [install] Error 1
make[3]: *** [gpllib] Error 2
[snip]

This is a potential issue. In ${S}/com32/gpllib/Makefile file,
install target wants to copy $(SRC)/../gplinclude to
$(INSTALLROOT)$(COM32DIR)/include/ directory, but in ${S}/com32/lib/Makefile
file, the install target will remove $(INSTALLROOT)$(COM32DIR)/include
directory. We need to do com32/lib first.

The patch make com32/gpllib depends on com32/lib to fix this issue.
