Abort when binutils ld is used with dynamic linking on ARM
The binutils linker on ARM emits unnecessary R_ARM_COPY relocations
which breaks tables-next-to-code in dynamically linked modules. This
check should be more selective but there is currently no released
version where this bug is fixed. See
https://sourceware.org/bugzilla/show_bug.cgi?id=16177 and
https://ghc.haskell.org/trac/ghc/ticket/4210#comment:29 for details.
