When configuring the otf2 dependency, CFLAGS, CXXFLAGS, CC and CXX are explicitly specified, but LDFLAGS is not. As a consequence, LDFLAGS is picked up from the environment (if set). In some build configurations, the LDFLAG from the environment is not compatible with the rest of the compiler/linker configuration options specified in CMakeLists.txt, resulting in the configure script failing. This patch make sure to specify an empty LDFLAGS when configuring otf2 build to avoid such issues. Bug: SWDEV-477693
