Note that this method of profiling the kernel is clang-native and isn't

Top-of-tree clang says that it's const:
$ gcc a.c -O2 && ./a.out
a is a const.
$ clang a.c -O2 && ./a.out
a is a const.

general, but there are some tools out there that expect the build id
to be of a certain length, i.e. the BFD style's length, because BFD is
more prevalent. The obvious response "well, why don't they just change
the expected length?" is difficu
ld's --build-id defaults to "sha1" style, while lld defaults to "fast".
The build IDs are very different between the two, which may confuse
programs that reference them.
