From ec93451443fe6d52305241b49265265ba434547c Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN\"" Date: Sat, 4 Jan 2014 16:19:18 +0100 Subject: libc/uClibc: add option to enable fenv Support for fenv.h is a little bit more tricky that enabling it only for x86-32 is not right. Add an option for the user to choose whther to install fenv.h or not. Signed-off-by: "Yann E.
