Fixes a bug causing AArch64 gating tests to fail

Fixes a bug causing AArch64 gating to fail

Hmm - it looks like I need to update the binutils-devel rpm to provide the required package config files.

In the meantime however I have created annobin-10.88 which does not have a requirement on pkgconfig(binutils-devel).

The failure is a false positive. The BTI_PLT flag is only set in F36 and Rawhide AArch64 binaries. In F35 binaries it is (deliberately) absent.

I need to add a F35 profile to annocheck - and probably encode a way for it to automatically set the profile based upon the input filename.

This update has been unpushed.
