 GCC 8.4 miscompiles dwarf2expr.c with -O2 or -O1 for earmv7hf{,eb}, which
 results in crashes described in the PRs. No upstream fixes up to now. So,
 let us disable optimization for this file.
 
 Note that this affects only earmv7hf{,eb} as far as I can see. Crashes do
 not occur neither for earmv6hf{,eb} nor earmv7{,eb}.
