The PHP source code comes with the PCRE library, which does not depend on the external PCRE library during compilation. Therefore, you do not need to compile the PCRE library and configure CPPFLAGS and LDFLAGS parameters:
CPPFLAGS = "-I/png/dev/android/compiled/usr/include "\
LDFLAGS = "-static-L/png/dev/android/compiled/usr/lib "\
