-php: force cross-compilation
-
-In its configure script, PHP detects whether we're cross-compiling or
-not, by compiling and running a simple C program. Depending on whether
-cross-compiling has been detected or not, then PHP enables or disables
-the AC_TRY_RUN tests (which verify the availability of something by
-*executing* a program, which, by definition, cannot work in
-cross-compilation mode).
-
-This works just fine when the target architecture is ARM or PowerPC
-and the build machine is x86 or x86_64. Unfortunately, when the target
-architecture is x86_64 and the build machine is also x86_64, the
-cross-compilation mode detection concludes that we are not
-cross-compiling, because it succeeds in running this small program.
-
-However, while it succeeds in running this basic small program, some
-other programs executed later through AC_TRY_RUN tests do not work,
-because they have target library dependencies that are not available
-on the build machine. For example, the libxml2 test fails to *run*
-because libxml2 is not available on the build machine, only in the
-target/staging directories. So trying to run a program linked against
-libxml2, on the build machine, simply doesn't make sense.
-
-We fix this problem by just forcing PHP to think that we're
-cross-compiling (which is always the case with Buildroot, as we're at
-the moment never building PHP for the host). Unfortunately, the
-configure.in file dates back from the autoconf 2.13 era, so the
-configure script does not understand the ac_cv_prog_cc_cross cache
-variable, and we cannot easily regenerate the configure script using
-our package autoconf version. The easiest solution is therefore to
-simply patch the configure script to make the cross-compilation test
-fail: we replace the execution of the program by a call to false,
-which always fail, leading the configure script to understand that we
-*are* cross-compiling.
