Yes, that change hard coded linux ABI values for
AT_HWCAP, AT_SWCAP2, AT_HWCAP3, and AT_HWCAP4 .

For the FreeBSD OS: AT_HWCAP, AT_HWCAP3, and AT_HWCAP4
differ in its ABI.

If there are any other of the names that might be of
OS ABI definitions, they would also be at potential
issue for some operating systems.
