Building with debug symbols

[ebruno]

I can see the -g flag in the compile , see sample below:
gcc -E -DARCH=x86_64 -DPLATFORM=efi -DSECUREBOOT=0 -fstrength-reduce -fomit-frame-pointer -falign-jumps=1 -falign-loops=1 -falign-functions=1 -m64 -mno-mmx -mno-sse -fshort-wchar -Ui386 -Ulinux -DNVALGRIND -fpie -mno-red-zone -Iinclude -I. -Iarch/x86/include -Iarch/x86_64/include -Iarch/x86_64/include/efi -Os -g -ffreestanding -Wall -W -Wformat-nonliteral -fno-stack-protector -fno-dwarf2-cfi-asm -fno-exceptions -fno-unwind-tables -fno-asynchronous-unwind-tables -Wno-address -g -Werror -ffunction-sections -fdata-sections -include include/compiler.h -DASM_TCHAR='@' -DASM_TCHAR_OPS='@' -DOBJECT=dhcpopts -Wno-error -M net/dhcpopts.c -MG -MP | sed 's/\.o\s*:/_DEPS +=/' > bin-x86_64-efi/deps/net/dhcpopts.c.d
[DEPS] net/fcoe.c

Here is the final link command.

ld -m elf_x86_64 -q -S --gc-sections -static -T scripts/efi.lds -u _efi_start --defsym check__efi_start=_efi_start -u obj_snp --defsym check_obj_snp=obj_snp -u obj_intelx --defsym check_obj_intelx=obj_intelx -u obj_config --defsym check_obj_config=obj_config -u obj_config_efi --defsym check_obj_config_efi=obj_config_efi --defsym pci_vendor_id=0 --defsym pci_device_id=0 -e _efi_start bin-x86_64-efi/version.snp--intelx.efi.o bin-x86_64-efi/blib.a -o bin-x86_64-efi/snp--intelx.efi.tmp \
--defsym _build_id=`perl -e 'printf "0x%08x", int ( rand ( 0xffffffff ) );'` \
--defsym _build_timestamp=1549298277 \
-Map bin-x86_64-efi/snp--intelx.efi.tmp.map
objdump -ht bin-x86_64-efi/snp--intelx.efi.tmp | perl ./util/sortobjdump.pl >> bin-x86_64-efi/snp--intelx.efi.tmp.map
./util/elf2efi64 --subsystem=10 bin-x86_64-efi/snp--intelx.efi.tmp bin-x86_64-efi/snp--intelx.efi

When attempt to load the file in to gdb I get
