[PATCH v4] Cygwin: define OUTPUT_FORMAT and SEARCH_DIR for AArch64

[Radek Barton via Cygwin-patches]

Hello.

Sending the version with `SEARCH_DIR("=/usr/lib/w32api")` only, with detailed 
commit message added. I've also removed semicolon for `SEARCH_DIR` as it's not 
needed and other directives do not use it.

This patch defines binutils output binary format for AArch64 which is 
pei-aarch64-little.

Since =/usr/lib/w32api resolves to $SYSROOT/usr/lib/w32api and Fedora 
cross-build takes libraries from
/usr/aarch64-pc-cygwin/sys-root/usr/lib/w32api, the 
SEARCH_DIR("/usr/x86_64-pc-cygwin/lib/w32api"); is
redundant and can be removed.
