Subject: set up Global Offset Table in recon
X-Git-Tag: v0.9.7~164
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=df2023a6cb82708badcf4425100e790080c24079;p=libvpx

set up Global Offset Table in recon

global values were being referenced, but the GOT was not being set up.
as the GOT is only required for PIC, this issue wasn't caught in the
default configuration.
