introduce --enable-large-address-aware
Add a configure knob for mingw32 and 64 toolchains to default passing
--large-address-aware to the linker, when creating 32-bit binaries.
-Wl,--disable-large-address-aware can still reverse its effects.
for gcc/ChangeLog
* configure.ac: Introduce --enable-large-address-aware
to define MINGW_DEFAULT_LARGE_ADDR_AWARE.
* doc/install.texi: Document it.
* configure, config.in: Rebuilt.
* config/i386/mingw32.h (LINK_SPEC_LARGE_ADDR_AWARE): Define,
based on MINGW_DEFAULT_LARGE_ADDR_AWARE.
(LINK_SPEC): Insert it.
* config/i386/mingw-264.h: Likewise.
