HOST_SYS="aarch64-oe-linux"
So the equivalent to the COMPATIBLE_OS would be:
COMPATIBLE_HOST ?= ".*-linux.*"
So it COULD be used in most cases.
When I tried this before though, I could get it to work in a multiconfig
setting.
Specifically what I tried was setting, in my local.conf:
COMPATIBLE_HOST ?= ".*-linux${LIBCEXTENSION}${ABIEXTENSION}"
And then in the recipes:
COMPATIBLE_HOST = ".*-elf"
COMPATIBLE_HOST_arm = ".*-eabi"
But then the second one matches the linux ABIEXTENSION and broke..
So really the issue is that I -only- ever want to match on the OS part of
the "SYS" string. And done to the multiple natures of the '-', it's
difficult to get right.
I didn't try something complex like: [^-]-[^-]-eabi
