--- Comment #4 from Andreas Krebbel <krebbel at linux dot ibm.com> ---
Since GCC 12 we always emit @PLT at brasl symbols already:
commit 0990d93dd8a4268bff5bbe48aa26748cf63201c7

IBM Z: Use @PLT symbols for local functions in 64-bit mode
This helps with generating code for kernel hotpatches, which contain
individual functions and are loaded more than 2G away from vmlinux.
This should not create performance regressions for the normal use
cases, because for local functions ld replaces @PLT calls with direct
calls.
That previous GCCs omit this isn't a problem since ld makes sure to jump
through PLT also for PC32DBL.
