Summary: app-emulation/virtualbox-7.0.22 fails to build with specific CFLAGS producing too big PXE NetBiosBinary

Description ChaosEngine 2025-01-03 09:30:23 UTC 
When using specific CFLAGS="-march=native -O2 -pipe -fomit-frame-pointer -funroll-loops" stable (amd64) virtualbox-7.0.22 fails to build tripping over bin2c size verification for PXE NetBiosBinary
However when I remove "-funroll-loops" from it build succeeds with probably binary made smaller and check succeeds.
The same happens if I leave "-funroll-loops" and change src/VBox/Devices/PC/ipxe/Makefile.kmk with bigger size limit (bin2c -min 32 -max 59...)

Reproducible: Always

Steps to Reproduce:
1. # emerge -vaB =app-emulation/virtualbox-7.0*
2. fails to build with specific CFLAGS
3.
Actual Results:  
Error output with usage of internal bin2c:
portage-tmp/app-emulation/virtualbox-7.0.22/work/VirtualBox-7.0.22/out/linux.amd64/release/obj/bin2c/bin2c: size=57372 - Not 32768-57344b in size!

Expected Results:  
build with no problem an smaller binary or omit size verification check?

The problem can be overcome with /etc/portage/env/specificCFLGS.conf with no funrollloops present.
