statvfs build error

Issue Description

Hi, When I built 245459.0.0 myself on branch master, I got a build error like this:
/Users/guizhong/dev/workspace/jsc-android-buildscripts/build/target/webkit/Source/WTF/wtf/posix/FileSystemPOSIX.cpp:422:9: error: no matching constructor for initialization of 'statvfs'
_if (statvfs(fileSystemRepresentation(path).data(), &fileSystemStat)) {

1 error generated.
And "jsc_fix_build_error_statvfs.patch" applied. Would you give me a clue how to fix it? It's the best way that you could publish a new tag on version 245459.0.0. Thanks!!
