eglibc: Remove eglibc support
As posted on http://www.eglibc.org/ ==================== EGLIBC is no longer developed and such goals are now being addressed directly in GLIBC. ==================== I'm not interested in maintaining build support for unsupported software. Older branches of crosstool-ng continue to have eglibc support. If you find issues with older branches, I'm always open to pull requests. Removing eglibc also frees up glibc cleanup and build optimization. Signed-off-by: Bryan Hundven <bryanhundven@gmail.com>
