[Buildroot] [git commit] webkitgtk24: fix MIPS64 n64 ABI detection

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=4c551f459470056740f824c6bec491d2ca2945ec
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

webkitgtk24 is failing to compile for MIPS64 n64 because the ABI is not
detected correctly. It causes failures like these ones:

./Source/JavaScriptCore/runtime/JSCJSValueInlines.h:201:53: error: cast
from 'JSC::JSCell*' to 'int32_t {aka int}' loses precision
[-fpermissive]

[snip]

./Source/WTF/wtf/StdLibExtras.h:137:5: error: static assertion failed:
bitwise_cast size of FromType and ToType must be equal!
