This removes a spurious \r at $gcc_{major,minor} in configure on cygwin.
Details:
The EOL output of conftest.exe for windows was \r\n . Now it's only \n .
The output of conftest is used with sh command substitutions which trim
trailing newlines, but not all windows shells consider \r\n as newline.
E.g. msys2 and busybox (for windows) were designed for tight integration
with windows apps and their shells do trim \r\n, but cygwin sh is closer
to POSIX and trims only \n - leaving \r at the string.
