Subject: gcov: add support for GCC 14
Date: Mon, 10 Jun 2024 11:27:43 +0200
Using gcov on kernels compiled with GCC 14 results in truncated 16-byte
long .gcda files with no usable data. To fix this, update GCOV_COUNTERS
to match the value defined by GCC 14.
Tested with GCC versions 14.1.0 and 13.2.0.
