Subject: collapse euidaccess to a call to faccessat
X-Git-Tag: v0.9.13~87
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=89384f78ce79efba22ab3a77e50c3f2a95233f8c;p=oweals%2Fmusl.git

collapse euidaccess to a call to faccessat

it turns out Linux is buggy for faccessat, just like fchmodat: the
kernel does not actually take a flags argument. so we're going to have
to emulate it there.
