According to https://en.wikipedia.org/wiki/Page_(computer_memory)#Multiple_page_sizes
, the value set to 2^21 (2MB) is to high for some processors but ok with x86 / x86_64 processors.
For instance, for ARMv7, 2^16 (64KB) is fine, but higher value is not

Description:
------------
The following commit introduced a regression in raspberry compilation host arm-linux-gnueabihf :
https://github.com/php/php-src/commit/62ded6efbcb41e24a505117f8de5b70d56a98f57

The linker flags do not seem compatible with my arch and produce a badly linked executable.



Test script:
---------------
./configure CFLAGS= CXXFLAGS= --enable-cli --disable-phpdbg --disable-all
--build=arm-linux-gnueabihf --disable-cgi && make -j4
sapi/cli/php --version

Expected result:
----------------
PHP 8.0.0-dev (cli) (built: Jul  9 2019 08:04:41) ( NTS )
Copyright (c) The PHP Group
Zend Engine v4.0.0-dev, Copyright (c) Zend Technologies


Actual result:
--------------
Segmentation fault

$ ldd sapi/cli/php
        not a dynamic executable
