[Ecls-list] configure and custom debug flags

[Kamil Shakirov]

Hi Juan,

Running configure script with supplied custom debug parameters eg. -- 
with-debug-cflags="-ggdb -O0" still gets overridden with optimization  
flags -O2 and -O3:

gcc -DECLDIR="\"/Users/kamil/local/lisp/ecl/lib/ecl-9.8.4\"" -I. -I/ 
Users/kamil/temp/ecl/build -I/Users/kamil/temp/ecl/src/c -I../ecl/gc - 
DECL_API -DECL_NO_LEGACY -ggdb -O0 -g -O2 -fPIC -fno-common -O3 - 
D_THREAD_SAFE -Ddarwin -c  -o gfun.o tmp.c

I wanted to turn off inlining.
