lz4 @1.9.3: does not build universal with arm64/x86_64 on an Intel system ./gen_manual: Bad CPU type in executable

Description (last modified by kencu (Ken))

it may not build arm64 at all, but this is a universal build on a BigSur Intel system:

hmmm. that's interesting. It does build arm64, it seems:

<http://packages.macports.org/lz4/lz4-1.9.3_0.darwin_20.arm64.tbz2>

during the build, it generates a file in the architecture being built to build the manual I guess:

% file ./lz4-1.9.3-arm64/contrib/gen_manual/gen_manual
./lz4-1.9.3-arm64/contrib/gen_manual/gen_manual: Mach-O 64-bit executable arm64

Intel systems can build this arm64 executable, but they can't run it, ergo the failure.

one fix is to turn off the generation of the manual by using build.target allmost:

% port -v installed lz4
The following ports are currently installed:
  lz4 @1.9.3_0+universal (active) platform='darwin 20' archs='arm64 x86_64' date='2021-01-10T13:13:03-0800'

No doubt Ryan has a better idea.

that was an elegant fix I never would have thought of. Thanks!
