dumper: avoid linker problem when libbfd depends on libsframe

Browse Source 
A recent binutils version introduced `libsframe` and made it a
dependency of `libbfd`. This caused a linker problem in the MSYS2
project, and once Cygwin upgrades to that binutils version it would
cause the same problems there.

Let's preemptively detect the presence of `libsframe` and if detected,
link to it in addition to `libbfd`.
