Thanks for analyzing this.
I think reverting would be backward - we should clearly move forward. One
way forward is to simply declare PCH unsupported with stabs.
The issue can be reproduced on x86_64 with -gstabs btw:
make check-gcc RUNTESTFLAGS="--target_board=unix/-gstabs pch.exp"

Another hack would be to s/asm_out_file/dbx_out_file/ in dbxout.c and
switch it to a temporary file during PCH generation, in the handle_pch
hook then read its contents and store it into the PCH.
