[Qemu-devel] [PATCH] sparc-linux-user: Fix missing symbols in .rel/.rela.plt sections

[Aurelien Jarno <aurelien@aurel32.net>]

Fix .rel.plt sections in the output to not only include .rel.plt
sections from the input but also the .rel.iplt sections and to define
the hidden symbols __rel_iplt_start and __rel_iplt_end around
.rel.iplt as otherwise we get undefined references to these when
linking statically to a multiarch enabled libc (using STT_GNU_IFUNC).
