[vbox-dev] VirtualBox-5.1.20a fails to compile - linux 32-bit

[John Frankish]

After adjusting src/libs/xpcom18a4/Makefile.kmk to look for libIDL-config-2, compiling vbox fails with:

kBuild: bin2c iPxeBiosBin - /usr/src/VirtualBox-5.1.20/out/linux.x86/release/obj/iPxeBiosBin/iPxeBiosBin.rom => /usr/src/VirtualBox-5.1.20/out/linux.x86/release/obj/iPxeBiosBin/iPxeBiosBin.c
/usr/src/VirtualBox-5.1.20/out/linux.x86/release/obj/bin2c/bin2c -min 32 -max 56 -mask 0x1ff -export NetBiosBinary /usr/src/VirtualBox-5.1.20/out/linux.x86/release/obj/iPxeBiosBin/iPxeBiosBin.rom /usr/src/VirtualBox-5.1.20/out/linux.x86/release/obj/iPxeBiosBin/iPxeBiosBin.c
/usr/src/VirtualBox-5.1.20/out/linux.x86/release/obj/bin2c/bin2c: size=54171 - Not aligned!
kmk: *** [/usr/src/VirtualBox-5.1.20/out/linux.x86/release/obj/iPxeBiosBin/iPxeBiosBin.c] Error 1

Is it possible to perform this step manually with different parameters to fix things?
