syslinux hdt.c32 (Hardware Detection Tool) is broken since AlpineLinux v3.9
hdt.c32 (part of syslinux package) fails with following diagnostics:
Undef symbol FAIL: exp
Failed to load libgpl.c32
Failed to load COM32 file hdt.c32This is known issue with gcc8, Debian patch exists.
Seems like it’s still not fixed upstream.
AlpineLinux prior to v3.9 is unaffected AFAIK.

main/syslinux: Apply Debian's patch to fix HDT.
With the current GCC 8.2.0 from Debian, a section of code calling pow() in
zzjson_parse.c is turned into a sequence calling exp(). Since no exp()
implementation is available in syslinux those optimizations need to be
disabled.
Closes #10546
