The line looks over-quoted as it is in single quotes and IMHO the
following was actually intended (or do I just miss a quoting level):
's,^#define[[:space:]]{1,}BOOT_TRAMPOLINE[[:space:]]{1,},,p'

"{1,}" is equivalent to "+", so
's/^#define[[:space:]]+BOOT_TRAMPOLINE[[:space:]]+//p'
should be equivalent (and since we have no path names, we can use "/").
Kind regards,
