From: "Jan Beulich" <JBeulich@xxxxxxxx>
Subject: x86-64: fix vDSO build
Certain ld versions (observed with 2.20.0) put an empty .rela.dyn section
into shared object files, breaking the assumption on the number of
sections to be copied to the final output. Simply discard any empty
SHT_REL and SHT_RELA sections to address this.
