What I see is this in Documentation/kbuild/makefiles.txt

LDFLAGS Generic $(LD) options

Flags used for all invocations of the linker.
Often specifying the emulation is sufficient.

Example:
#arch/s390/Makefile
LDFLAGS := -m elf_s390
Note: ldflags-y can be used to further customise
the flags used. See chapter 3.7.



I have two questions then:
1- Can I use that as a bash variable? Like "LDFLAGS=--emit-relocs make"
or
2- Editing arch/x86/Makefile with
KBUILD_LDFLAGS := -m --emit-relocs elf_$(UTS_MACHINE)

Thanks for your help.
