Subject: uml: fix CONFIG_STATIC_LINK=y build failure with newer glibc
From: Roland McGrath <[email protected]>
commit aa5fb4dbfd121296ca97c68cf90043a7ea97579d upstream.
With glibc 2.11 or later that was built with --enable-multi-arch, the UML
link fails with undefined references to __rel_iplt_start and similar
symbols. In recent binutils, the default linker script defines these
symbols (see ld --verbose). Fix the UML linker scripts to match the new
defaults for these sections.
