This was removed from bionic by commit c82c0b7e072491da4818e7de37411fbb2055fce1 in 2014-06. The symbols are still in NDK cruft for LP32, but no longer in the NDK's libc.so. Microsoft points out that we should probably remove the header too. Bug: 11156955 Change-Id: Id463f8f20d3d8c4428f6aecb317577d78ccad215
