Commit 7ebde1bf67daa24ea7735f2b2d7000d074e2ba93 by douglas.yung
Add a shim for setenv on PS4 since it does not exist.
A few years back a similar change was made for getenv since neither
function is supported on the PS4 platform.
Recently, commit d889d1e added a call to setenv in compiler-rt which was
causing linking errors because the symbol was not found. This fixes that
issue by putting in a shim similar to how we previously dealt with the
lack of getenv.
