Prboom add unconditionally -O2 in CFLAGS and triggers a segfault with this
toolchain.

See -0s and -O2 in this command line:
/home/autobuild/instance-0/output/host/usr/bin/sh-linux-gnu-gcc -DHAVE_CONFIG_H
-I. -I..   -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64
-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -Os  -Wall
-Wno-unused -Wno-switch -Wextra -Wno-missing-field-initializers -Winline
-Wwrite-strings -Wundef -Wbad-function-cast -Wcast-align -Wcast-qual
-Wdeclaration-after-statement -ffast-math -O2 -fomit-frame-pointer -I../src
-I/home/autobuild/instance-0/output/host/usr/sh4a-buildroot-linux-gnu/sysroot/usr/include/SDL
-D_GNU_SOURCE=1 -D_REENTRANT -c r_filter.c

-O2 is added from CFLAGS_OPT in configure.ac, so we need to remove it and
autoreconf prboom to avoid this issue.
But if we use BR2_OPTIMIZE_2 we still have the compiler bug... So it's more a
toolchain issue...

I'm ok to disable prboom with this toolchain.

qhull needs gcc >= 4.4:
