# Per some websites I've seen to add `-gcflags "all=-N -l"`, the gcflags seem poorly if at all documented
# the best I could dig up is -N disables optimizations and -l disables inlining which should make debugging match source better.
# Also remove the -s and -w flags present in the normal build which strip the symbol table and the DWARF symbol table.
