configure: Fix detection of BTF header to enable the BTF front-endupstream-master
Cestmir Kalina reported that running configure with --enable-btf with
no BTF header present on the system wrongly leads to the BTF
front-end of libabigail being enabled, and later leads to
compilation/installation errors.
This patch fixes that by ensuring that the ENABLE_BTF variable set by
the --enable-btf option handling code is not reused later during
actual btf.h header file detection code.
* configure.ac: Use a new HAS_BTF_HEADERS to store the detection
status for the btf.h header. Emit a better notice message when
the BTF header file is found.
