How does this make it a reason ?
libfprtl will always be specific to the distribution it was compiled on.
If tuned, it should be tuned to that system.
Just like libc or any library close to the system is. Don't try to copy
a binary libc.so from a SuSE to a Fedora system, it won't work.
Just like you shouldn't copy kernel32.dll from Windows XP to Windows 2003.
