Cross-compiling a port

[Martin Waschbüsch]

Hi there,

how would I go about cross-compilinga port for another ARCH?
E.g. I am running 11.1-RELEASE on amd64 and would like to compile a port for i386.
It does not seem to be enough to set the ARCH and TARGET_ARCH environment variables:

e.g. something like

cd /usr/ports/archivers/zip
env 'TARGET_ARCH=i386 ARCH=i386' make

will still produce a 64bit binary.

file /usr/ports/archivers/zip/work/stage/usr/local/bin/zip
/usr/ports/archivers/zip/work/stage/usr/local/bin/zip: ELF 64-bit LSB executable, x86-64, version 1 (FreeBSD), dynamically linked, interpreter /libexec/ld-elf.so.1, for FreeBSD 11.1, FreeBSD-style, stripped

so I must be missing something here.
