From 381616e77ae7610f8fe07b9e0eb193d613fb3bf7 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sun, 30 Jun 2013 21:29:09 +0200 Subject: Introduce BR2_TOOLCHAIN_USES_{UCLIBC, GLIBC} Currently, when we need to do a conditional on the type of C library used, we need to take into account the three toolchain backends. As we are going to add eglibc support to the Buildroot toolchain backend, it would become even uglier, so this patch introduces two new hidden options: BR2_TOOLCHAIN_USES_UCLIBC and BR2_TOOLCHAIN_USES_GLIBC, that exist regardless of the toolchain backend. The entire Buildroot code base is converted to use those options. Note that we have intentionally created only one option (BR2_TOOLCHAIN_USES_GLIBC) for both glibc and eglibc, since they are essentially the same, as far as Buildroot is concerned.
