Issue tracking for build on Ubuntu

[marcuswu0814]

Original build command in Makefile isswift build --disable-sandbox -c release -Xswiftc -static-stdlib can't work on Linux platform.

Know issue:

SR-2205 Linker fails when linking to Foundation if -static-stdlib flag is present - Swift
SR-7038 in 4.1, -static-stdlib doesn’t seem to work anymore - Swift

The static-stdlib can't be used on Linux platform.

So, currently adding build-for-linux command remove the -Xswiftc -static-stdlib. Make this issue to track this problem.
