toolchainfile.cmake.in: do not force the CMAKE_{C, CXX}_FLAGS to the cache
Fix #7280 [1]
When the FORCE option is passed to the set command, the variable is
added/updated in the CMake cache every single time CMake processes this
command.
Because the toolchainfile.cmake prepends architecture/toolchain flags
to the CMAKE_{C,CXX}_FLAGS, this makes the CFLAGS being updated in the
generated Makefiles each time one reconfigures its project. So it
forces the compilation of everything, even when nothing has changed.
