[OE-core] [PATCH V2] tclibc-musl.inc: fix bfd "cannot make copy relocation for protected symbol" issues

[liu.ming50 at gmail.com]

From: Ming Liu <peter.x.liu at external.atlascopco.com>

Quite a few such compiling issues were found when I was building with
following configs:
...
MACHINE = "beaglebone"
TCLIBC = "musl"
DISTRO_FEATURES_append = " ld-is-gold"
...

fixed by adding bfd binding now ldflags.
