Hey all,

Thank you Bernhard and Adrian for debugging this. I have opened an unblock
request for ghc to see if RT will allow us to fix this for buster.

[#928882] https://bugs.debian.org/928882

Running the `utils/llvm-targets/gen-data-layout.sh` script[1], outputs
the following triplet for arm-unknown-linux-gnueabi:

  ("arm-unknown-linux-gnueabi", ("e-m:e-p:32:32-i64:64-v128:64:128-a:0:32-n32-S64", "arm7tdmi", "+soft-float -fp-only-sp -d16 -vfp2 -vfp3 -fp16 -vfp4 -fp-armv8 -neon -crypto +strict-align"))

The ARM7TDMI processor core implements the ARM architecture v4T, so it
looks like the correct value for armel, but it would be great if someone
from the debian-arm team could verify that the rest of the flags are OK.

Hopefully, we can fix this for buster.
