Subject: remove processing of DT_JMPREL from dynamic linker stage 1 bootstrap
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=09db855b35709aa627d7055c57a98e1e471920ab;p=musl

remove processing of DT_JMPREL from dynamic linker stage 1 bootstrap

the DT_JMPREL relocation table necessarily consists entirely of
JMP_SLOT (REL_PLT in internal nomenclature) relocations, which are
symbolic; they cannot be resolved in stage 1, so there is no point in
processing them.
