Subject: x86/boot: do not create unwind tables
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~1017
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=647fde45730771f47b438ee495e16fd4e9cf9629;p=xen.git

x86/boot: do not create unwind tables

This way .eh_frame section is not included in *.lnk and *.bin files.
Hence, final e.g. reloc.bin file size is reduced from 408 bytes to
272 bytes and it contains only used code and data.
