Subject: [PATCH] ld: Add -Bsymbolic-non-weak-functions
This option is a subset of -Bsymbolic-functions: only STB_GLOBAL are
considered. Vague linkage functions are STB_WEAK. A vague linkage
function may have different addresses in a -Bsymbolic-functions linked
shared object and outside the shared object.
-Bsymbolic-non-weak-functions can keep pointer equality while providing
most benefits: (a) fewer JUMP_SLOT (symbol lookups) (b) avoid PLT
entries for default visibility defined functions.
