Problem description

Building libxml2 2.15.0 in the Termux builder (aarch64) fails at the tests stage when linking runtest:

ld.lld: error: undefined symbol: glob
ld.lld: error: undefined symbol: globfree
clang: error: linker command failed with exit code 1

On Android, glob(3)/globfree(3) are provided by libandroid-glob, not bionic. With Python bindings/tests enabled, the runtest executable needs to link against -landroid-glob.

Minimal fix that works in practice (recipe-only):

• Add libandroid-glob to TERMUX_PKG_DEPENDS
• Add LDFLAGS+=" -landroid-glob" inside termux_step_configure()

This is sufficient because the current build path propagates LDFLAGS to test linking.

     export TERMUX_MESON_ENABLE_SOVERSION=1
     termux_step_configure_meson
 }

Notes:

• The _XOPEN_SOURCE (600 vs 700) warnings are benign and unrelated.
• If some environments don’t propagate global LDFLAGS to tests, a target-scoped link arg for runtest in src/meson.build would also work, but the above minimal change fixes the issue in the current builder.

What steps will reproduce the bug?

1. (Optional) clean caches/markers:

   rm -rf ~/.termux-build/libxml2* ~/.termux-build/python-libxml2*
   rm -f /data/data/.built-packages/libxml2 /data/data/.built-packages/python-libxml2

2. Build:

   ./build-package.sh -a aarch64 libxml2

3. Observe link error for runtest:

   ld.lld: error: undefined symbol: glob
   ld.lld: error: undefined symbol: globfree
   

What is the expected behavior?

• libxml2 builds successfully on Android, including tests (or tests link without undefined symbols).
• No undefined references to glob/globfree during runtest link.
