Subject: [PATCH] Fix musl build
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch fixes cross-compiling U-Boot tools with the musl C library:
  * including <sys/types.h> is needed for ulong
  * defining _GNU_SOURCE is needed for loff_t

Tested for target at91sam9261ek_dataflash_cs3.
