[oe] [meta-initramfs][PATCH] klibc.inc: lazy assign GCCPIE in case security_flags.inc was not included

[Andrea Adami]

fix build error (GCCPIE is unset):

EXTRA_KLIBCAFLAGS=${SECURITY_CFLAGS} -Wa,--noexecstack
EXTRA_KLIBCLDFLAGS=${@-z relro -z now -pie if  else } -z noexecstack
| make: invalid option -- 'z'
| make: invalid option -- ' '
