From bbef0a871dc2d50d3a86b96fa61cef2fd36bd828 Mon Sep 17 00:00:00 2001 From: Bernd Kuhls Date: Sat, 6 Feb 2016 12:51:20 +0100 Subject: [PATCH] package/boost: Disable fenv support with uClibc The boost build system does not recognize the fact that fenv.h is an optional module in uClibc and tries to use it even if UCLIBC_HAS_FENV is disabled. This patch disables fenv support completely when compiling with a uClibc-based toolchain.
