[Bug debug/39539] New: wrong function name and line numbers with -g -O2 option

["MR dot Swami dot Reddy at nsc dot com" <gcc-bugzilla at gcc dot gnu dot org>]

With -g -O2 option, crx-elf-gcc generates wrong line numbers and function
names.
==
/tmp/ccrrZsJf.o: In function `090312 (experimental)':
/home10/swami/test.c:5: undefined reference to `_f1'
collect2: ld returned 1 exit status
===

Expected output could be:
===
/tmp/ccEJcFRs.o: In function `main':
/home10/swami/test.c:6: undefined reference to `_f1'
collect2: ld returned 1 exit status
----


testcase: "test.c"
====

int f = 1;
extern int f1 ();

main () {
   f1();
}
