 New Comment:

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.

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
