Description:
------------
Xcode libs should have lowest precedence, but build system tries to link with Xcode libs and link fails.

It seems not only -L flag, but also -I flag (and others) have the same issue.

All supported/dev branches have this problem.



Test script:
---------------
$ YACC=/usr/local/opt/bison27/bin/bison ./configure --with-iconv=/usr/local/opt/libiconv && make -j 4

You'll need brew's bison27 and libiconv.

Expected result:
----------------
Link should succeed. 

Actual result:
--------------
cc -I/usr/local/opt/libiconv/include -g -O2 -fvisibility=hidden   -L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib -L/usr/local/opt/libiconv/lib  -Wl,-rpath,/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib -Wl,-rpath,/usr/local/opt/libiconv/lib ext/date/php_date.o ext/date/lib/astro.o ext/date/lib/dow.o ext/date/lib/parse_date.o ext/date/lib/parse_tz.o

I build PHP on OSX on occasions and I still have this issue.
The cause is EXTRA_LDFALGS/EXTRA_LDFALGS_PROGRAM define

-L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib

before libs specified by configure options. If you have the same issue, remove OSX/Xcode system lib from EXTRA_LDFALGS/EXTRA_LDFLAGS_PROGRAMS.

Is this still an issue with any of the actively supported PHP
versions[1]?
