Revert "meta: build with -ffreestanding" 
This reverts commit b0c4e6fd2f.

After investigation, this is related to builtin functions. Using
-fno-builtin is a less invasive way to solve the problem. However this
appears to be a bug [1]; in theory fat LTO objects should solve that. I
will handle this matter at the fxSDK level by adding -fno-builtin right
and experimenting with the bugfix in binutils 2.43.
