[Buildroot] xlib libXt build problem

Hi!

I've been trying to setup a buildroot configuration (in this case an  
x86 environment, although PPC is next...) and have run into a snag  
getting an X11 environment included.   I've done pretty much the  
minimum configuration needed - setting the X Windows System server to  
tinyx and turning on xorg-server.

But the build is hanging in the middle of the X11 build, in  
particular when building the makestrs.c module in the xlib libXt  
package.   It fails with an error:

	makestrs.c:33:21: error: X11/Xos.h: No such file or directory

I've put the full output at the end of this message.  (The string  
library function warnings bother me too, but they're at least just  
warnings...)  I've done quite a lot of searching and trying to figure  
this out before coming here, and it looks to me like the compiler  
command line is missing an include path to the staging directory's / 
usr/include directory.   That seems to be correctly referenced in the  
packages xlib_libXt.mk file (in XLIB_LIBXT_CONF_ENV), but there is  
also a patch (xlib_libXt-1.0.5-makestrs-nocc.patch) in the package  
folder which sets it up to use gcc (the HOST_CC part of the patch)  
and doesn't seem to take into account the staging directory.

I'm making an educated guess that the patch effectively overrides the  
XLIB_LIBXT_CONF_ENV setting (or something else isn't including that  
setting), but I'm not sure what the right fix for this is.   A brute  
force fix would be something like changing the patch to read:

	HOST_CC=gcc -I$(STAGING_DIR)/usr/include

...but is that the correct approach here?  And why hasn't anything  
regarding this issue come up before?  It seems odd that nobody else  
is running into this.
