sed and xentools413

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

xentools413 is repeatably failing with

./config/ioapi.h:17:10: fatal error: config/local/ioapi.h: No such file or directory
   17 | #include <config/local/ioapi.h>

In a very round about way this seems to be related to

  [DEPS] arch/x86/drivers/net/undiisr.S
sed: 1: "s/\.o\s*:/_DEPS +=/": RE error: trailing backslash (\)
gmake[7]: *** Deleting file 'bin/deps/arch/x86/drivers/net/undiisr.S.d'
  [DEPS] arch/x86/transitions/librm.S
sed: 1: "s/\.o\s*:/_DEPS +=/": RE error: trailing backslash (\)
gmake[7]: *** Deleting file 'bin/deps/arch/x86/transitions/librm.S.d'
...

apparently from

pkgsrc/sysutils/xentools413/work.x86_64/ipxe-1dd56dbd11082fb622c2ed21cfaced4f47d798a6/src/Makefile.housekeeping

   sed 's/\.o\s*:/_DEPS +=/' > $(BIN)/deps/$(1).d

gets me a successful build.

I'm assuming a WORKSFORME response for xentools413, so wondering
whether something changed in -current sed that would explain the
above.
