Enable -Bsymbolic and -Bsymbolic-functions to PIE
Before binutils 2.26, -Bsymbolic and -Bsymbolic-functions were also
applied to PIE so that "ld -pie -Bsymbolic -E" can be used to export
symbols in PIE with local binding. This patch re-enables -Bsymbolic
and -Bsymbolic-functions for PIE.
PR ld/19615
* ld.texinfo: Document -Bsymbolic and -Bsymbolic-functions for
PIE.
