--- Comment #1 from Maninder Singh <maninder1.s at samsung dot com> ---
Fixing [#89347] gc-sections doesn't remove unused bss section variables.
gc-section works well only for bss section if global variables initialised
with 0 explicitly and not with uninitalised one.
Reason is -fdata-sections does not make separate section for bss symbols
which are not initialised with 0 explicitly.
due to which gc-section does not remove bss symbols which are not
getting used in binary.
