Sam Clegg 98dbbfd851 [WebAssembly] Remove use of lld -flavor flag 
This flag is deprecated. The preferred way to select the lld
flavor is by calling it by one of its aliases.

David Greene 8d819a9973 [WebAssembly] Force use of lld for test/Driver/wasm-toolchain.c(pp) 
lld is the only supported linker that works for WebAssembly, so ensure
clang is using it for this test. This gets the tests passing when
configuring clang to use a different linker by default.

Sam Clegg 7892ae44b4 [WebAssembly] Don't pass -ffunction-section/-fdata-sections 
llvm currently forces both of these to true to passing them
is redundant.

Sam Clegg 471d7afdf0 [WebAssembly] Add crt1.o with calling lld 
Also, for OS unknown targets like wasm, don't include
'unknown' in the library path. This is a fix for rL316719.

Sam Clegg 8202e86a99 [WebAssembly] Add default -allow-undefined-file to linker args 
Also, don't use the outdated lib32/lib64 naming of files
within the sysroot. The more modern/flexible approach
IIUC is to use seperate sysroots or /lib/<target-tripple>
and /include/<target-tripple>.
