Linker scripts shipped by TI require to have every
interrupt vector in a separate section with a specific name:

SECTIONS
 {

  __interrupt_vector_XX   : { KEEP (*(__interrupt_vector_XX )) } > VECTXX
  ...

}

Follow the requirement emit the section for every vector
which contain address of interrupt handler:

  .section  __interrupt_vector_XX,"ax", at progbits
  .word %isr%
