I noticed that when offloading from my x86_64 box to my aarch64 machine
target gets (%current-system) from the originating system, not from the
system doing the building. I'm testing moving the '(let ((triplet ...'
code down from the top of the definition to inside the arguments. I
didn't see a difference with 'guix build -d' for x86_64 from x86_64, but
the derivation did change with the planned offload to an aarch64
machine.
I looked into gcc-2.95 more than I wanted to last week with GHC-4.08,
would it help if we specified we wanted armv4 or armv4t or strongswan
instead of "generic"?
