boost_stacktrace_addr2line does not build

[lightupmemory]

Hello, I'm trying to cross build boost for M1 on an Intel mac. Everything goes fine, except addr2line does not build. From the configuration check, it shows

    - libbacktrace builds      : no [2]
    - libbacktrace builds      : no [3]
    - addr2line builds         : no [2]
    - addr2line builds         : no [3]

below is my script

chmod u+x bootstrap.sh tools/build/src/engine/build.sh

./bootstrap.sh --with-python=/usr/bin/python3

./b2 install architecture=arm \
"cxxflags=-std=c++17 -arch arm64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -mmacosx-version-min=11.0" \
"cflags=-arch arm64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -mmacosx-version-min=11.0" \
"linkflags=-arch arm64 -Wl,-syslibroot,/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -mmacosx-version-min=11.0" \

building environment

• operating system: macOS 12.0.1
• Xcode version: 12.4

It seems that macOS doesn't have addr2line at /usr/bin/addr2line. I'm wondering how does boost check for addr2line builds. Moreover, building boost natively (either on intel or M1) and cross building for x86_64 on M1 all generate boost_stacktrace_addr2line. Is it the limitation on intel mac for cross building?

I got a similar problem when cross building for Android. The cause seems to be that the build script detects addr2line and libbacktrace by trying to compile and run some C++ code

https://github.com/boostorg/stacktrace/blob/75b7986f9799184ecd679d86273532cb54e6a0dc/build/Jamfile.v2#L42-L52

Unfortunately, as we are cross compiling, the code is built for the target system and won't run on host system.
