Ruby and clang 3.4

[Antoine Brodin]

Hi there,

With clang 3.4  (imported 3 days ago in head),  ruby has problems
configuring / building dl.so.
Logs for ruby19 and ruby 20 are available at
http://package21.nyi.freebsd.org/bulk/head-default-baseline/2014-02-18_15h22m08s/logs/errors/ruby-1.9.3.484_1,1.log
 and  http://package21.nyi.freebsd.org/bulk/head-default-baseline/2014-02-18_15h22m08s/logs/errors/ruby20-2.0.0.353_4,1.log

This is due to clang 3.4 rejecting -fno-defer-pop

I have the following patch for ruby19:
