Remove '-flto' from clangd compiler command line by default

Browse Source 
Linker-time-optimization flag should not have any effect on clangd,
so we may remove it from the compiler command line by default when
feeding clangd with the source files. gcc supports the
optimization level that should be applied for the relative binaries.
The level can be specified as the number N following by the -flto=[N]
argument. clangd meanwhile doesn't know about this option and throws
the 'Unsupported argument '1' to option '-flto=' error.
