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. From-SVN: r265130
