We shouldn't use NO_PIE_CFLAGS and NO_PIE_FLAG with CXX_FOR_BUILD
when CXX_FOR_BUILD != CXX.  This patch adds BUILD_NO_PIE_CFLAGS
and BUILD_NO_PIE_FLAG to use with CXX_FOR_BUILD.  They are set to
NO_PIE_CFLAGS and NO_PIE_FLAG when build machine == host machine.
Otherwise, they are set to NO_PIE_CFLAGS_FOR_BUILD and
NO_PIE_FLAG_FOR_BUILD.

* Makefile.in (NO_PIE_CFLAGS): New.
(NO_PIE_FLAG): Likewise.
(NO_PIE_CFLAGS_FOR_BUILD): Likewise.
(NO_PIE_FLAG_FOR_BUILD): Likewise.
(BUILD_NO_PIE_CFLAGS): Likewise.
(BUILD_NO_PIE_FLAG): Likewise.
(COMPILER): Replace @NO_PIE_CFLAGS@ with $(NO_PIE_CFLAGS).
(LINKER): Replace @NO_PIE_FLAG@ with $(NO_PIE_FLAG).
(BUILD_CFLAGS): Replace @NO_PIE_CFLAGS@ with
$(BUILD_NO_PIE_CFLAGS).
(BUILD_CXXFLAGS): Likewise.
(BUILD_LDFLAGS ): Replace @NO_PIE_FLAG@ with
$(BUILD_NO_PIE_FLAG).
* configure.ac (BUILD_NO_PIE_CFLAGS): New.  AC_SUBST.
(BUILD_NO_PIE_FLAG): Likewise.
(NO_PIE_CFLAGS_FOR_BUILD): Likewise.
(NO_PIE_FLAG_FOR_BUILD): Likewise.
* configure: Regenerated.
