From eef4d4f80cc0e88e4a1d8f1060df3088cd479adc Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Fri, 8 Feb 2019 21:04:24 +0100 Subject: math: Enable sysdeps override sysdeps/ia64/fpu/bits/math-finite.h exists and will be installed on ia64, but during the build, the default math/bits/math-finite.h file is used, which is wrong.
