RFR: 8237944: webview native cl "-m32" unknown option for windows 32-bit build

[Guru Hb]

cl : Command line warning D9002 : ignoring unknown option '-m32'

post fix for "https://trac.webkit.org/changeset/242724/webkit" makes use of cross compiling 32 bit JSC in a 64 bit and its holds good only for Linux. 
'-m32' flag is gcc specifc and on windows cl.exe (visual studio) doesn't recognize this flag.
