# - pgac_cv_prog_cc_ldflags__Wl___as_needed: Inform that the linker supports as-needed. It's
#   not stricly necessary but avoids unnecessary linking of binaries.
# - USE_UNNAMED_POSIX_SEMAPHORES: Avoid using System V semaphores which are disabled on Android.
# - ZIC=...: The zic tool is used to build the time zone database bundled with postgresql.
#   We specify a binary built in termux_step_host_build which has been patched to use symlinks
#   over hard links (which are not supported as of Android 6.0+).
#   There exists a --with-system-tzdata configure flag, but that does not work here as Android
#   uses a custom combined tzdata file.
