Subject: [PATCH] MIPS/readelf: Remove extraneous null GOT data check
Null data is handled gracefully throughout in MIPS GOT processing, with
addresses printed normally and unavailable data shown as `<unknown>' by
`print_mips_got_entry', and special processing code for GOT[1] doing an
explicit check. Remove an unwanted null GOT data check then, introduced
with commit 592458412fb2 in the course of addressing PR binutils/12855.

* readelf.c (process_mips_specific): Remove null GOT data check.
Upstream-Status: Backport
CVE: CVE-2017-9041 patch #1
