crotchet-freebsd fails to build u-boot (master)

[Winston Smith]

Firstly, I'm new here!  Im trying to get FreeBSD up and running on the
BBB booting from the eMMC.

I'm using Patrick Kelsey's BBB-multi-install-config.sh script
(https://github.com/pkelsey/crochet-configs/blob/master/BBB-multi-install-config.sh)
with crotchet-freebsd building FreeBSD-11-CURRENT and u-boot master.


  CHK     include/config/uboot.release
  CHK     include/generated/version_autogenerated.h
  CHK     include/generated/timestamp_autogenerated.h
  UPD     include/generated/timestamp_autogenerated.h
  HOSTCC  tools/dumpimage.o
  HOSTCC  tools/image-fit.o

It looks like it's picking up the sha256.h header from /usr/include
rather than in u-boot-master/include.  I believe I'm using Clang for
the u-boot compilation, as I built the xdev tools as follows:

make XDEV=arm XDEV_ARCH=armv6 xdev


I ran a build with u-boot-master and 10-stable xthe other day and I
didn't run into this.  I can only assume that the sha256.h is new in
11-current?

Any ideas?  Thanks!
