Everything in bash script.
It actually might be working. What I did was I was looking for a 
confirmation like this:

$ ps -FC rpmbuild --cols 9999
UID        PID  PPID  C    SZ   RSS PSR STIME TTY          TIME CMD
appmgr   24855 24835  0 44512  6772  16 17:33 pts/0    00:00:00 rpmbuild 
--define "_MKL 1" --define "_mic 1"

waiting to see those quotation marks(single or double) in there, but.. 
it turns out that it works actually when ps is not showing them, like:

$ ps -FC rpmbuild --cols 9999
UID        PID  PPID  C    SZ   RSS PSR STIME TTY          TIME CMD
appmgr   24855 24835  0 44512  6772  16 17:33 pts/0    00:00:00 rpmbuild 
--define _MKL 1 --define _mic 1

and then vars(in a bash script, all in such a script) are simply declared:
...
export _definition1='_MKL 1'
rpmbuild --define "${_definition1}" --define "${_definition2}"

without! any escaping of quotes.
