New description:

 Hello!

 I have successfully bootstrapped ghc for sparc64 on Debian unstable by
 cross-compiling it on amd64, then installing it manually into a build root
 and rebuild the Debian package.

 Unfortunately, the buildds can currently neither compile ghc itself nor
 any Haskell packages as gcc always passes "-relax" to the GNU linker which
 will fail as ghc passes "-Wl,-r" (1):

 libraries/terminfo/ghc.mk:3: recipe for target 'libraries/terminfo/dist-
 boot/build/System/Console/Terminfo/Base.o' failed
 }}}

 This issue has already been fixed in ghc but that was for sparc only and
 not sparc64 (2).

 Thus, in order to be able to apply the same fix from (2), ghc needs to add
 sparc64 to its list of known architectures (currently "sparc64" matches to
 "ArchUnknown" in aclocal.m4") and then extend the fix from (2) to match
 *both* sparc *and* sparc64 (please don't drop sparc here).

 In particular, I suggest adding sparc64 in the same way that Alpha, Mipseb
 and Mipsel were added (3), thus matching "sparc64" to "ArchSPARC64", then
 extending the if-clause from (4) to set "-Wl,-no-relax" for *both*
 ArchSPARC *and* ArchSPARC64.

 Thanks,
 Adrian
