cannot build u-boot-zynq-zybo* on macOS: Bus Error

[David Young <dyoung%pobox.com@localhost>]

On an M1 iMac I am trying to build some u-boot packages from -current
including u-boot-zynq-zybo-z7.  I am not having much luck and I am not
sure what to try next.

The trouble is that before the build finishes, a build tool, mkimage,
crashes with a Bus Error:

  LD      spl/u-boot-spl
  OBJCOPY spl/u-boot-spl-nodtb.bin
  CAT     spl/u-boot-spl-dtb.bin
  COPY    spl/u-boot-spl.bin
  MKIMAGE spl/boot.bin
Bus error 
gmake[1]: *** [scripts/Makefile.spl:192: spl/boot.bin] Error 138
gmake: *** [Makefile:1539: spl/u-boot-spl] Error 2
*** Error code 2

Stop.
bmake[1]: stopped in
/Volumes/Case-sensitive/nbsd/pkgsrc/sysutils/u-boot-zynq-zybo-z7

So close!

Here is some info about the crashing tool,

$ file ../../../pkgobj//wrkobjdir/sysutils/u-boot-zynq-zybo/work/u-boot-2018.11/tools/mkimage
../../../pkgobj//wrkobjdir/sysutils/u-boot-zynq-zybo/work/u-boot-2018.11/tools/mkimage: Mach-O 64-bit executable arm64

$ otool -L ../../../pkgobj//wrkobjdir/sysutils/u-boot-zynq-zybo/work/u-boot-2018.11/tools/mkimage
../../../pkgobj//wrkobjdir/sysutils/u-boot-zynq-zybo/work/u-boot-2018.11/tools/mkimage:
	/Volumes/Case-sensitive/nbsd/pkg/lib/libssl.3.dylib (compatibility version 3.0.0, current version 3.0.0)

	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1311.100.3)

Looks like the tool crashes while still in the dynamic loader,

By the way, I updated pkgsrc just a day or two ago.  It's unchanged
except for a change I made to u-boot-zynq-zybo-z7/Makefile.  Because
a source file in the package tried to #include an OpenSSL header (I
believe it was called <openssl/evb.h>), I added some lines:

--- u-boot-zynq-zybo-z7/Makefile	12 Aug 2021 07:25:59 -0000
