[PATCH] cygwin: fix --tsaware, add --large-address-aware

Subject: [PATCH] cygwin: fix --tsaware, add --large-address-aware
Authentication-results: sourceware.org; auth=none

This patch fixes two issues with LINK_SPEC on Cygwin targets:

1) --tsaware makes sense only for EXEs, not DLLs.

2) Under WoW64 (32-bit Cygwin on 64-bit Windows), Cygwin applicationscan access up to 4 GiB of address space (for DLLs, Cygwin heap, mmap()s,etc.) if they are linked with --large-address-aware. Because of howCygwin implements fork(), the ability to use this extra space is a hugebenefit. This flag too is only for EXEs, not DLLs.


Patch attached.
