[U-Boot] [PATCH] libfdt: Fix redefined uintptr_t warning for USE_HOSTCC

[Jerry Van Baren <gvb.uboot@gmail.com>]

Compiling U-Boot in an old OS environment (RedHat-7.3  :-)  gives the
following warnings from FDT:

include/libfdt_env.h:50: warning: redefinition of 'uintptr_t'
/usr/include/stdint.h:129: warning: 'uintptr_t' previously declared here

Fix: Protect the definition of uintptr_t when compiling on the host
system.

Dear Wolfgang,

Try this, it looks like a simple oversight.  I'm not sure why we don't
see it on a "modern" ;-) linux.

Best regards,
