php: fix linker errors by setting ac_cv_func_dlopen=no

Browse Source 
The autoconf variable `ac_cv_func_dlopen` controls whether `dlopen()`
is available without linking `libdl.so`.  But that doesn't work:

 tmp-glibc/work/aarch64-oe-linux/php/7.2.10-r0/recipe-sysroot-native/usr/bin/aarch64-oe-linux/../../libexec/aarch64-oe-linux/gcc/aarch64-oe-linux/8.2.0/ld: ext/sqlite3/libsqlite/sqlite3.o: undefined reference to symbol 'dlsym@@GLIBC_2.17'
 tmp-glibc/work/aarch64-oe-linux/php/7.2.10-r0/recipe-sysroot-native/usr/bin/aarch64-oe-linux/../../libexec/aarch64-oe-linux/gcc/aarch64-oe-linux/8.2.0/ld: tmp-glibc/work/aarch64-oe-linux/php/7.2.10-r0/recipe-sysroot/lib/libdl.so.2: error adding symbols: DSO missing from command line

Leave `ac_cv_lib_dl_dlopen=yes`, because that's the one which controls
whether `-ldl` is needed.
