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

[Michael Tokarev <mjt@tls.msk.ru>]

This patch was submitted more than a year ago (at Jan-2012).
Is it still needed?  If yes, why it hasn't been applied?

It still applies cleanly to the current git, with the exception
of s|^|ldscripts/| - sparc.ld moved from the top directory to
ldscripts/.

(Ref: http://patchwork.ozlabs.org/patch/135267 )

Thanks,
