Khem Raj - June 9, 2012, 4:43 p.m.
In some cases we need to specify linker flags and right
now we do not have a way to communicate that to cmake
based systems. cmake defines CMAKE_C_LINK_FLAGS and CMAKE_CXX_LINK_FLAGS
for these needs. This patch therefore defines two local variables
namely OECMAKE_C_LINK_FLAGS and OECMAKE_CXX_LINK_FLAGS which
can be altered by recipes to tweak linker flags
