supposedly the situation is much better in 7.8, which uses the system
linker. Unfortunately, we don’t know, because it FTBFS for other
reasons:

I grepped through the ghc commit messages and identified these people
(CC’ed) as having worked on arm-related stuff in the recent past:

 Luke Iannini <lukexi at me.com>
 Ben Gamari <bgamari.foss at gmail.com>
 Stephen Paul Weber <singpolyma at singpolyma.net>
 Karel Gardas <karel.gardas at centrum.cz>

They might know better what is supposed to work, and why it does not
work on Debian yet. And maybe the prospect of hardware access to fast
build machines can spark renewed enthusiasm in that direction.

Greetings,
Joachim
