disabled by default; add SYMVER_ENABLED=true to /etc/make.conf to enable it. libc should get a version bump before this is enabled by default. Reviewed by: davidxu

# All library objects contain FreeBSD revision strings by default; they may be
|
|
# excluded as a space-saving measure. To produce a library that does
|
|
# not contain these strings, add -DSTRIP_FBSDID (see <sys/cdefs.h>) to CFLAGS
|
|
# below. Note: there are no IDs for syscall stubs whose sources are generated.
|
|
# To include legacy CSRG sccsid strings, add -DLIBC_SCCS and -DSYSLIBC_SCCS
|
|
# to CFLAGS below. -DSYSLIBC_SCCS affects just the system call stubs.
