Help on building the OpenBTS / OsmoBTS Transceiver branch

I tried the instructions here: https://osmocom.org/projects/baseband/wiki/CalypsoBTS

on a pretty clean and up to date Debian 10 vm and had no problems.

I used the arm-none-eabi-* packages that come with Debian.

arm-none-eabi-gcc --version
arm-none-eabi-gcc (15:7-2018-q2-6) 7.3.1 20180622 (release) [ARM/embedded-7-branch revision 261907]

Maybe you need to do some steps like

$ sudo make uninstall
$ make distclean
$ git pull --rebase
In libosmocore and libosmo-dsp?

I used the fixeria/trx branch as mentioned in the wiki page above.
