Description:
------------
When I build php with --enable-memory-limit make install fails due to hitting the memory limit.


Reproduce code:
---------------
Use:

LD_LIBRARY_PATH='/usr/local/ldap' \
CFLAGS='-O2 -std1 -ifo -taso' \
CXXFLAGS='-std1 -O2 -ifo -taso' \
CC='cc' \
CXX='cxx' \
'./configure' \
'--with-openssl' \
'--enable-bcmath' \
'--with-ndbm' \
'--with-dbm' \
'--enable-dbase' \
'--enable-filepro' \
'--enable-ftp' \
'--with-gd' \
'--with-ttf' \
'--with-java=/usr/opt/java141' \
'--with-mysql' \
'--with-oci8' \
'--with-oracle' \
'--enable-shmop' \
'--enable-sockets' \
'--enable-sysvsem' \
'--enable-sysvshm' \
'--enable-wddx' \
'--enable-dba=shared' \
'--enable-calendar' \
'--enable-exif' \
'--enable-discard-path' \
'--enable-dbx' \
'--enable-ctype' \
'--with-hyperwave' \
'--enable-mailparse' \
'--enable-mbstring' \
'--enable-mbstr-enc-trans' \
'--enable-memory-limit' \
'--with-ldap=/usr/local/ldap' \
'--with-inifile' \
'--with-flatfile' \
'--enable-dio' \
'--enable-sysvmsg' \
'--with-zlib' \
'--with-zlib-dir=/usr/local' \
'--with-jpeg-dir=/usr/local' \
'--with-png-dir=/usr/local' \
'--with-cdb=shared'

build it using 'make'.  Then run 'make install'.


Expected result:
----------------
I expect PHP to be installed.


Actual result:
--------------
