1. mk: Don't build jemalloc with -g3 …

   By default, jemalloc is building itself with -g3 if the local compiler supports
   it. It looks like this is generating a good deal of debug info that windows
   isn't optimizing out (on the order of 18MB). Windows gcc/ld is also not
   optimizing this data away, causing hello world to be 18MB in size.
   
   There's no current real need for debugging jemalloc to a great extent, so this
   commit manually passes -g1 to override -g3 which jemalloc is using. This is
   confirmed to drop the size of executables on windows back to a more reasonable
   size (2.0MB, as they were before).
   
   Closes rust-lang#14144
