Description:
------------
Not able to compile the modules for Alpine Linux even when adding libc 
 compatibility

I've followed the instructions located here.
https://github.com/php/pecl-database-ibm_db2

Alpine Linux is a very popular, and incredibly small distro which has seen widespread usage as a base docker container. 

Test script:
---------------
docker run -it php:7.3-fpm-alpine sh
apk update && apk add autoconf musl-dev gcc make re2c file libc6-compat
cd /opt
curl -O https://public.dhe.ibm.com/ibmdl/export/pub/software/data/db2/drivers/odbc_cli/linuxx64_odbc_cli.tar.gz  \
       && tar -zxf linuxx64_odbc_cli.tar.gz \
export IBM_DB_HOME=/opt/clidriver \
       && export LD_LIBRARY_PATH=/opt/clidriver/lib \
       && export PATH=/opt/clidriver/bin:$PATH
curl -O https://pecl.php.net/get/ibm_db2-2.0.8.tgz \
      && tar -zxf ibm_db2-2.0.8.tgz 
cd ibm_db2-2.0.8 \
      && phpize --clean \
      && phpize && ls \
  && ./configure --with-IBM_DB2=/opt/clidriver \
  && make \
  && make install \
  && docker-php-ext-enable ibm_db2

php --version

Actual result:
--------------
/usr/local/lib/php/extensions/no-debug-non-zts-20180731 # php --version
