T11758 testcase help needed

[Thomas Miedema]

Hi Alex,

You're deleting hacks that were added for ancient version of binutils
(added in 14a5aadb84c34dbe2bee129ed80fdfa1fb12e3e0 in 2005
and b8a64b8ec9cd3d8f6e3f23e44312c4903eccac45 in 2007).

I think that if you submit your patch without a test, there's a good chance
it will get accepted.

Thomas
