[Buildroot] [PATCH 1/1] package/php: use correct cxxflags for icu support

[Bernd Kuhls]

Php lacks "-std=c++11", provided by icu-config, when compiling icu
support leading to a build failure:

/home/peko/autobuild/instance-1/output/host/usr/sh4-buildroot-linux-uclibc/sysroot/usr/include/unicode/umachine.h:347:13:
 error: 'char16_t' does not name a type
     typedef char16_t UChar;

Fixes
