X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=7448b33d2f632aeb82fb0db488c7848468c2061e;p=openbsd

On armv7, remove symbols that are also present in our libc.  Because of the
EABI aliases these can lead to duplicate symbol errors, especially when
mixing code compiled with gcc and clang.  The intention is to revert this
once we convert armv7 to hardfloat.
