Subject: Merge x86 and x86_64 handling in configure.
X-Git-Tag: 1.9.9-b1~916
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=08855dd12acee578705d9e51648a0c337aeeaeb4;p=thirdparty%2Fzlib-ng.git

Merge x86 and x86_64 handling in configure.
Add parameter to disable new strategies.
Add parameter to disable arch-specific optimizations.
(This is just the first few steps, more changes needed)
