Description:
------------
Similarly to what someone reported on Bug #43341, when compiling PHP 5.3 snap on AIX 5.3 (using IBM XLC and shipped tools) `make` succeeds but no php cli is generated at all.

Note the "echo '\" was supposed to build sapi/cli/php but it just echoes those two lines and nothing else.

I could workaround that by cleaning up (by hand) the BUILD_CLI variable after Makefile is generated. I am not sure why the original command is not working or whether (and why) it was generated in a faulty way. Maybe some tool shipped with AIX is the responsible for that ?

Follows the diff that works for me (sorry, no unified output format in AIX's diff):

20c20
< BUILD_CLI = echo '\#! .' > php.sym && echo >>php.sym && nm -BCpg `echo $(PHP_GLOBAL_OBJS) $(PHP_CLI_OBJS) | sed 's/\([A-Za-z0-9_]*\)\.lo/\1.o/g'` | $(AWK) '{ if ((($$2 == "T") || ($$2 == "D") || ($$2 == "B")) && (substr($$3,1,1) != ".")) { print $$3 } }' | sort -u >> php.sym && $(LIBTOOL) --mode=link $(CC) -export-dynamic $(CFLAGS_CLEAN) $(EXTRA_CFLAGS) $(EXTRA_LDFLAGS_PROGRAM) $(LDFLAGS) -Wl,-brtl -Wl,-bE:php.sym $(PHP_RPATHS) $(PHP_GLOBAL_OBJS) $(PHP_CLI_OBJS) $(EXTRA_LIBS) $(ZEND_EXTRA_LIBS) -o $(SAPI_CLI_PATH)

Reproduce code:
---------------
$ ./configure
$ make
$ make test

Expected result:
----------------
sapi/cli/php to be generated.

Actual result:
--------------
$make

Build complete.
Don't forget to run 'make test'.

$ make test
        echo '\
\

Build complete.
Don't forget to run 'make test'.

ERROR: Cannot run tests without CLI sapi.
