The only, but ugly, way I have managed to find around this atm is:
LIBS="-lpthread" LDFLAGS="-Wl,--start-group" /path/to/configure

Description:
------------
php's configure script has multiple places where it filters out -lpthread from $LIBS
before ac_fn_c_try_link
This is likely ok for shared, but causes problems with static libs.
One example of this is when building openssl static.
# pkg-config openssl --libs
-L/usr/src/php-build/install/OpenSSL_1_1_1h/lib -lssl -lz -lcrypto -lpthread -ldl
Problem is, when configure tries to check this rule, it filters out some libs from
what it was told by pkg-config:
(looping through $XXXX_LIBS)
case $ac_ii in
c|c_r|pthread*) ;;
*)
LIBS="$LIBS -l$ac_ii"
;;
esac
(end loop)
ac_fn_c_try_link
ac_fn_c_try_link basically does:
$CC -o conftest$ac_exeext $CFLAGS $CPPFLAGS $LDFLAGS conftest.$ac_ext $LIBS >&5
and in my case then, results in the following libs:
-lssl -lz -lcrypto -ldl
note -lpthread missing, and the test failing.
I have not managed to find a way around this without modifying the configure file, adding -lpthread
where it needs to be.
The rest of the actual build is just fine after manually adding -lpthread to just the relevant
tests.
