[OE-core] [PATCH 1/3] glibc: print PN when bbwarn

[Robert Yang]

The current warning is:
WARNING: glibc: unable to generate header for spray.x

Which is easier to debug than:
WARNING: unable to generate header for spray.x

And remove the file before generate it again to fix the warning when
recompile:
file `bootparam_prot.h' already exists and may be overwritten
WARNING: unable to generate header for bootparam_prot.x
file `nlm_prot.h' already exists and may be overwritten
WARNING: unable to generate header for nlm_prot.x
[snip]
