strace says:

open("/home/tteras/aports/testing/php7/src/php-7.0.3/modules/xml.so", O_RDONLY|O_LARGEFILE) = 3
read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\240\26\0\0004\0\0\0"..., 936) = 936

After some more investigation, it seems that there's text relocations:

$ scanelf -t /home/tteras/aports/testing/php7/src/php-7.0.3/modules/*.so|grep TEXT
 TYPE   TEXTREL FILE 
ET_DYN TEXTREL /home/tteras/aports/testing/php7/src/php-7.0.3/modules/bz2.so 
ET_DYN TEXTREL /home/tteras/aports/testing/php7/src/php-7.0.3/modules/dom.so

ET_DYN TEXTREL /home/tteras/aports/testing/php7/src/php-7.0.3/modules/xml.so 

This sounds like CFLAGS or namely -fPIC is ignored somehow.
