Remove the bbappend that applied const qualifier fixes to libbpf.c.
The workaround was required for older kernel versions where building
perf with -Werror triggered warnings due to discarded const qualifiers
from strstr() and strchr().
The issue is resolved in the currently used linux-intel 6.18 kernel,
making this workaround no longer necessary.

perf: Fix const qualifier warnings in libbpf.c2026-03-13T15:45:44+00:00Yogesh Tyagiyogesh.tyagi@intel.com2026-03-13T15:42:43+00:00urn:sha1:1610818c25713c700f48c5428c151d0d02e4aa94
Fix compilation warnings when building perf with -Werror where const
qualifiers are discarded from pointers returned by strstr() and
strchr() functions in libbpf.c.
Both strstr() and strchr() return 'const char *' when given
'const char *' input parameters. The receiving variables must
preserve this const qualification to maintain const-correctness
and avoid compiler warnings.
Errors fixed:
libbpf.c:8179:13: error: assignment discards 'const' qualifier
from pointer target type [-Werror=discarded-qualifiers]
libbpf.c:11967:35: error: assignment discards 'const' qualifier
from pointer target type [-Werror=discarded-qualifiers]
This is a workaround for kernel 6.12.x. The issue is already fixed
upstream in kernel 6.13+ and can be removed when the kernel is updated.
