Tegra 2 processors have only 16 double-precision registers. The change introduced by8dcc108760("toolchain: ARM: Fix toolchain compilation for gcc 8.x") switched accidentally the toolchain for tegra target to cpu type with 32 double-precision registers. This stems from gcc defaults which assume "vfpv3-d32" if only "vfpv3" as mfpu is specified. That change resulted in unusable image, in which kernel will kill userspace as soon as it causing "Illegal instruction".

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
