.pc for Android contains invalid syntax

Bug report

Bug description:

Looking at the Android build here: https://www.python.org/downloads/android/

The .pc files look like this:

# See: man pkg-config
prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: Python
Description: Build a C extension for Python
Requires:
Version: 3.14
Libs.private: -ldl  -llog
Libs: -L${libdir} $(BLDLIBRARY)
Cflags: -I${includedir}/python3.14

The "Libs:" line contains some autotools internals instead of the library name resulting in linker errors like:

cannot find $(BLDLIBRARY): No such file or directory

Might be related to #115780

Disclaimer: The main reason I'm reporting this is that it also breaks the Cygwin build in the same way, but that's not a supported platform, so this is the next best thing. i.e. I've not actually tested on Android.

Work around broken pc file

Thanks for the report. I guess $(BLDLIBRARY) should probably be replaced with -lpython3.14. However, I'm not currently aware of anyone who uses the .pc file on Android, so I won't pick this up this myself just now.

Fair enough, I've hackily worked this around downstream now.

Work around broken pc file

configure: Work around broken pc file

This affects any package using Meson, which uses pkgconfig to detect Python, so I'll implement a workaround in cibuildwheel.

Example error:
