[google-4_6] fix issues of streaming lipo

[xur, 2012-06-07 00:03:13]

Hi,

This is for google-4_6 branch only.

It fixed a few issues:
(1) not passing pedantic flag from primary module to aux;
(2) not using pipe to generate iro file even -pipe specified;
(3) fix the case like -D"foo bar" option in auxiliary module.

Tested google internal benchmarks.

2012-06-06  Rong Xu  <xur@google.com>

	* gcc.c (RIPA_AUX_MOD_SPEC):not passing pedantic flag to aux
          modules.
          (ripa_invoke_as):not using pipe for iro file.
          (ripa_build_aux_mod_func):-D define can have space.
