commit a9bfffe59333fdc6785f3cc903188d1ead36539d

    Fix Linux fallocate tests for EOPNOTSUPP
    
    The fallocate syscall might fail on Linux due missing support from
    underlying filesystem (for instance some NFS versions).  This patch
    adds this check for fallocate tests.  It also moves tst-fallocate{64}
    to 'io' folder (since it is on fallocate{64} is built).
    
    Checked on x86_64.
    
    	* sysdeps/unix/sysv/linux/Makefile [$(subdir) = math] (tests): Move
    	tst-fallocate{64}.
    	* sysdeps/unix/sysv/linux/tst-fallocate-common.c: Check for EOPNOTSUPP
    	on syscall return.
