Fix world build with gcc-5

I saw that my prior pull request has not yet been picked so I took opportunity to update it with few more commits and remove the commits not needed for world builds out. With these world builds on OE-Core are succeeding for all supported qemu machines The gcc upgrade is not yet proposed since we are still in RC phase and as soon as 5.1.0 is released I will propose it for OE-Core

Khem Raj (14):
glibc, packagegroup-self-hosted, packagegroup-core-lsb: Consider
non-glibc libcs
insserv: Fix build with gcc5 and clang
xserver-xorg: Fix build with gcc-5
u-boot-mkimage: Backport fix from upstream to fix build with gcc-5
mdadm: Fix inline semantics
lttng-tools: Add extern qualifier to declarations in .h file
subversion: Add -P to CPPFLAGS
gnome-icon-theme: Needs nls.m4
gtk+: Correct function prototype
grub: Backport const qualifier fix for gcc-5
gummiboot: upgrade 43 -> 48+git
pkgconfig: Upgrade to latest git tip
fontconfig: Upgrade to 2.11.93
fontconfig: Fix pkgconfig file generation to not have absolute paths
