Fix ReLAPACK integration problems

1. Replaced all instances of "int" with "blasint"
2. Added string length as "hidden" third parameter in calls to fortran XERBLA

USE_TLS=1.

Change 64-bit detection as explained in #2056

Use POSIX getenv on Cygwin

The Windows-native GetEnvironmentVariable cannot be relied on, as
Cygwin does not always copy environment variables set through Cygwin
to the Windows environment block, particularly after fork().
