I have an example of this in _umtx_op_err.po contained in libpthread_p.a. The object file is created with the following command: cc -DPROF -O2 -pipe -DPTHREAD_KERNEL -I/usr/home/erik/freebsd/head/src/lib/libthr/../libc/include -I/usr/home/erik/freebsd/head/src/lib/libthr/thread -I/usr/home/erik/freebsd/head/src/lib/libthr/../../include -I/usr/home/erik/freebsd/head/src/lib/libthr/arch/amd64/include -I/usr/home/erik/freebsd/head/src/lib/libthr/sys -I/usr/home/erik/freebsd/head/src/lib/libthr/../../libexec/rtld-elf -I/usr/home/erik/freebsd/head/src/lib/libthr/../../libexec/rtld-elf/amd64 -I/usr/home/erik/freebsd/head/src/lib/libthr/../libthread_db -Winline -fexceptions -D_PTHREAD_FORCED_UNWIND -D_PTHREADS_INVARIANTS -DSYSCALL_COMPAT -std=gnu99 -Wsystem-headers -Werror -Wall -Wno-format-y2k -W -Wno-unused-parameter -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wno-uninitialized -Wno-pointer-sign -c /usr/home/erik/freebsd/head/src/lib/libthr/arch/amd64/amd64/_umtx_op_err.S -o _umtx_op_err.po This command leaves absolute paths in the symbol table.
