[Bug ld/24426] Binutils 2.28.1 segfault when presented (any) linker script on riscv64

--- Comment #5 from Alexander von Gluck IV <kallisti5 at unixzen dot com> ---
I just took the internal linker script and passed it back in, and it works as
expected.  Then I used an empty linker script and it segfaulted again.

Maybe a bug in 2.28.1 that was fixed by 2.29?  It feels like something missing
in the linker script results in the segfault.
