* nacl/GNUmakefile.in (CC, LD, NM, AR, AS, RANLIB, OBJDUMP, OBJCOPY)

  Rewrites these variables instead of PATH.
  NaCl port uses a toolchain which is specified by NACL_SDK_ROOT
  environment variable. Originally, NaCl build added the toolchain
  under the NACL_SDK_ROOT to the PATH. But updating PATH doesn't work
  on Mac.
  (RBCONFIG): Replaces configs with the variable updates above.

* configure.in: Thus it is no longer necessary to check $PATH.

Based on a patch by Takashi Toyoshima <toyoshim AT gmail.com>.
