GCC versions before 4.5 do not have the -fno-lto flag and give an error if it is used. The flag may also be unavailable on various other non-GCC compilers. Previously, the picolibc CMakeList.txt script assumed that the flag was available, and hard-coded it as an addition to the compiler flags. This patch improves compatibility by making use of the already existing "prohibit_lto" CMake target compiler property, which is set to the appropriate flag to disable LTO support, or unset if the compiler lacks such an option.
