From: Pu Lehui <pulehui@xxxxxxxxxx>
After commit b991fc520700 ("selftests/bpf: utility function to get
program disassembly after jit"), Makefile will link libLLVM* related
libraries to the user binary execution file when detecting that
feature-llvm is enabled, which will cause the local vmtest to appear as
follows mistake:
./test_progs: error while loading shared libraries: libLLVM-17.so.1:
cannot open shared object file: No such file or directory
Considering that the get_jited_program_text() function is a useful tool
for user debugging and will not be relied upon by the entire bpf
selftests, let's turn it off in local vmtest.
