Description:
------------
Hallo,

while trying to cross compile PHP via a bitbake recipe (openembedded.org), I discovered, that
somehow the build system of PHP turns of the Dynamic Loading support if it detects that PHP is being
cross compiled.

See configure-Script of PHP:

[...]
  if test "$found" = "yes"; then
    ac_libs=$LIBS
    LIBS="$LIBS -ldl"
    if test "$cross_compiling" = yes; then :
  found=no
else
[...]

As you can see, the configure script sets "found" to no for libdl/dlopen-tests, if
cross_compiling is enabled.
In my opinion (and according to my tests) there is no reason to do this, as overriding this manually
by setting -DHAVE_LIBDL as CFLAGS and adding -ldl to LDFLAGS leads to a PHP build that is
Dynamic-Loading-enabled and works without problems on the target machine.
