Says:
../wine-source/configure CFLAGS="-g -O1 -fno-optimize-sibling-calls
-fno-omit-frame-pointer -fno-inline"

IMHO these two are superfluous as:
 * "optimize-sibling-calls" is disabled in -O1 and enabled since -O2
 * "omit-frame-pointer" is disabled in -O0, -O1 and -O2

at least by comparing output of following two commands:
gcc -g -O1 -Q --help=common
gcc -g -O1 -fno-optimize-sibling-calls -fno-omit-frame-pointer -fno-inline -Q
--help=common

I tried that on Debian Stretch. Gcc (Debian 6.3.0-6) 6.3.0 20170205
