Newer versions of ld automatically emit .gnu.hash and .note.gnu.build-id
sections, which are not listed in the linker script, and will end up
breaking the build with an allocation conflict, e.g.,
/usr/bin/aarch64-linux-gnu-ld: section .note.gnu.build-id loaded at
[0000000000000000,0000000000000023] overlaps section .text loaded at
[0000000000000000,0000000000017dbf]
Since we don't require or care about these sections, update the linker
script so that they are discarded. Note that this involves emitting the
.note.gnu.build-id section into a non-allocatable segment to prevent the
linker from noticing that it is being discarded (and subsequently
complaining about it)
