kbuild: dwarf: use AS_VERSION instead of test_dwarf5_support.sh
The test code in scripts/test_dwarf5_support.sh is somewhat difficult
to understand, but after all, we want to check binutils >= 2.35.2
From the former discussion, the requirement for generating DWARF v5 from
C code is as follows:
- gcc + gnu as -> requires gcc 5.0+ (but 7.0+ for full support)
- clang + gnu as -> requires binutils 2.35.2+
- clang + integrated as -> OK
