I'm trying to cross-compile bytehound for aarch64
git clone https://github.com/koute/bytehound.git
cd bytehound
CC='aarch64-linux-gnu-gcc' cargo build --target aarch64-unknown-linux-gnu --release -p bytehound-preload
....
Compiling bytehound-preload v0.11.0 (/home/pawluch/temp/bytehound/preload)

What am I doing wrong with this cross-compilation?
I tried with sdk, where I passed also --sysroot and there is the same output
P.S.
I'm trying to recompile it since current bytehound I'm using crashes binaries for that architecture and I thought that maybe I'm using too old version which does not match some libs in the binary I'm trying to profile. It collects some data for ~5mins and then app is crashing. Profiled do not have any good backtrace ;(
Disabling shadow-based stack unwinding did not help. Maybe you have some idea what caused that problem?
