firmware/Makefile.inc: allow overlapping sections

The entire point of our linker scripts is to produce overlapping
segments/mappings/addresses. They are essential and required.

Starting from [1], not only LMA but also VMA areas are now checked
for overlaps (see also [2]). This results into linking errors:

  arm-none-eabi-ld: section .text.exceptions VMA
    [000000000080001c,0000000000800037] overlaps section
    .compal.reservedram VMA [0000000000800000,00000000008000fe]
  arm-none-eabi-ld: section .text.exceptions VMA
    [000000000080001c,0000000000800037] overlaps section
    .compal.loader VMA [0000000000800000,00000000008000ff]

Let's tell the linker that the overlaps are expected using its
command line option '--no-check-sections'.
