Bug #7451: r37911 breaks build on non gcc or non IA-32 platforms

Author: ngoto (Naohisa G.)
Status: Open

ruby -v: -

r37911 以降、__sync_val_compare_and_swap がリンク失敗したら必ず -march=i486 が付くため、

Sun(Oracle)の SolarisStudio 12.3 のccでは、-m はリンカに何かを渡すオプションらしく、
以下のようにminirubyのリンクに失敗します。Fujitsu C Compiler でも同様です。
