Atharva Lele b285c80143 toolchain/toolchain-wrapper: explicitly pass --build-id=none if BR2_REPRODUCIBLE
Build ID is added to binaries at link time. Building in different
output directories causes some packages to have different Build IDs,
thus resulting in non-reproducibility.

Adding "-Wl,--build-id=none" fixes this issue by disabling setting of
Build ID.

Diffoscope output for Build ID issue:
https://gitlab.com/snippets/1886180/raw

After this patch, build is reproducible - i.e. diffoscope does not
produce any output.
