With LLVM 23, bcc is failing to build when I tested with bpftrace.
I tested with command:

utils/docker-run support/testing/run-tests \
     -d dl -o output_folder \
     tests.package.test_bpftrace

It fails with error:

/buildroot/output_folder/TestBpftrace/build/bcc-v0.36.1/src/cc/bcc_debug.cc:151:68: 
error: no matching function for call to 
'llvm::MCContext::MCContext(llvm::Triple&, 
std::unique_ptr<llvm::MCAsmInfo>::pointer, 
std::unique_ptr<llvm::MCRegisterInfo>::pointer, 
std::unique_ptr<llvm::MCSubtargetInfo>::pointer, std::nullptr_t)'

So could you send a v2 of the series, adding before
the llvm bump, a bcc bump to 0.37:
https://github.com/iovisor/bcc/releases/tag/v0.37.0
which also includes a backport of:
https://github.com/iovisor/bcc/commit/dad0db93fd0f443b2a4f43bc2f23c621c9202516

Could you make sure the bcc or bpftrace runtime test works with that, 
please?
