*/builtin.mk: Disable for cross-build if executes target program.
We can't run target programs during cross-build, so we either need to
disable builtin detection or find another way to detect the target
program's version.
No change to native builds because this just makes some existing
logic conditional on native builds.

Log message:
Also set DYLD_LIBRARY_PATH=. (in addition to LD_PRELOAD) when generating
magic. Fixes build on macOS (Monterey and Snow Leopard tested) when file
is not already installed.

Log message:
Adjust previous use of LD_PRELOAD to fix Solaris 11 build, hoping it'll
fix the SmartOS bulk build (which gave similar errors, but which I
couldn't reproduce on my SmartOS or Tribblix systems).
Does not break:
- macOS 12.1
- NetBSD 9.2 and -current
- OpenBSD 7.0
- FreeBSD 13.0
- Tribblix m25.1
- CentOS 7 and 8
- Debian 9, 10, and 11
- Devuan 4
- Ubuntu 14, 16, 18, and 20
- Void

Log message:
On some Linux systems with a sufficiently old sysutils/file installed,
we get this error, followed by a bunch of warnings attempting to compile
magic anyway:
"lt-file: Compiled magic version [540] does not match with shared library \ 
magic version [538]"
Instead of using whatever libmagic might already be installed, use the
just-built libmagic. (There's probably a less hacky way.)

Log message:
sysutils: Replace RMD160 checksums with BLAKE2s checksums
All checksums have been double-checked against existing RMD160 and
SHA512 hashes

Log message:
sysutils: Remove SHA1 hashes for distfiles
