DanS 1c3523aac1 build(win): add -Wa,-mbig-obj to the mingw cross-compile flags
Large template/boost-heavy TUs (e.g. asyncrpcoperation.cpp) exceed the standard
PE/COFF ~32k-section limit under mingw-w64, which makes GNU ld emit
"dangerous relocation" on .pdata and crash (SIGSEGV) at link. The bigobj COFF
variant lifts that limit; this is the same flag Bitcoin Core sets for its mingw
host. Fixes the Windows daemon cross-compile.
