Subject: alpha: Require kernel version 2.6.0.
X-Git-Tag: glibc-2.16-ports-before-merge~289
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fe7b738e7a0cf88f28bb40f55daa4237733f290f;p=thirdparty%2Fglibc.git

alpha: Require kernel version 2.6.0.

The minimum version that supports TLS.  Also avoids having to
fix the build for ancient __ASSUME_* settings.
