[LLD] Linker crashes when trying to parse ':ALIGN'

[parth-07]

If there is no space between ":" and ALIGN, linker will misparse the following script:

SECTIONS
{
  S :ALIGN(4096) {}
}

Moreover, when recovering from this error, it will enter infinite recursion and overflow the stack.

Thank you @quic-akaryaki for finding this issue.
