Having the following error building on snapcraft's armhf builder:

:: {standard input}: Assembler messages:
:: {standard input}:26002: Error: selected processor does not support requested special purpose register -- `mrs r3,cntfrq_el0'

[tzcnt]

Working on this.

@ilya-fedin while I have your attention, mind taking a look at desktop-app/lib_crl#10 ?
