Remove a tab character from the definition of %__global_compiler_flags

From https://bugzilla.redhat.com/2083296:

> The issue is that some packages break up the flags at spaces,
> in order to look for specific flags or to add flags of their own.
>  The z3 package, for example, has some python code that does this:
>
>     def exec_cmd(cmd):
>         if isinstance(cmd, str):
>             cmd = cmd.split(' ')
>         ...
>
> The result is one of the commands in the list consists of a single tab character.
>  When that is passed to the compiler, the compiler does not like it at all.
