php7: update to 7.2.14

While at, add --with-pic to configure arguments. This prevents the following
build errors spotted by the build bots for i386 targets:

-snip-
...
ext/openssl/.libs/openssl.o: direct GOT relocation R_386_GOT32X against
`X509_REQ_free' without base register can not be used when making a shared object
...
-snap-

This parameter seems to make no difference on other targets, nor
improve or make worse the package size.

Run tested for i386 in VirtualBox VM and on Duckbill for mxs platform.
