Bill Wendling c054086630 Try to improve performance by using a read/write buffer instead of I/O. The calls to fwrite/fread can be very expensive. GCC avoids this by using a buffer to read and write from the file, thus limiting the number of fwrite/fread calls. <rdar://problem/13466086> llvm-svn: 181924		2013-05-15 21:31:22 +00:00

It is often convenient to be able to build compiler-rt libraries for a certain
platform without having a full SDK or development environment installed.

This makes it easy for users to build a compiler which can target a number of
different platforms, without having to actively maintain full development
environments for those platforms.

Since compiler-rt's libraries typically have minimal interaction with the
system, we achieve this by stubbing out the SDKs of certain platforms.
