[PHP-INSTALL] PHP compilation from source on FreeBSD 10

[Oriental Sensation]

Hello all,

I am trying to compile PHP from source on FreeBSD 10 using clang. The
compilation succeeds but for some reason, I get the opcache library
packaged as an ar archive and named libopcache.a (maybe got something
to do with PIC?)

I have no idea what is causing this to happen. For the record, the
same configure command when used on FreeBSD 9 branch followed by
compilation produced a working, shared opcache.so library.

The configure command:

./configure --prefix=/usr/local --with-xmlrpc
--with-pcre-regex=/usr/local --with-bz2=/usr --enable-zip
--with-openssl=/usr --with-iconv=/usr/local --with-mcrypt=/usr/local
--enable-mbstring --with-curl=/usr/local --with-libxml-dir=/usr/local
--with-xsl=/usr/local --enable-exif --enable-intl --enable-bcmath
--disable-debug --enable-cgi --disable-cli --with-imap=/usr/local
--with-imap-ssl --enable-calendar --with-mhash=/usr/local --with-gd
--with-freetype-dir=/usr/local --enable-gd-native-ttf --with-zlib=/usr
--with-png-dir=/usr/local --with-jpeg-dir=/usr/local
--with-mysql=/usr/local --with-mysqli=/usr/local/bin/mysql_config
--with-pdo-mysql=/usr/local --with-regex=php --enable-mbregex
--disable-sysvsem --disable-sysvshm --disable-shmop --enable-soap
--enable-sockets --enable-inline-optimization --enable-opcache
--without-pear --with-config-file-path=/usr/common/etc/php
--with-config-file-scan-dir=/usr/local/etc/php/cgi --enable-fpm
--with-fpm-user=www --with-fpm-group=www

Even if I add --without-pic the same happens.

One more thing I noticed: The configure script doesn't guess the
correct system type, instead it detects it as:
x86_64-unknown-freebsd10.0 (should be x86_64-amd64-freebsd10.0 maybe?)
Even if I specify a different system build, the same happens.

Any idea why OPCache is compiled as libopcache.a and not opcache.so?

Thanks in advance,
