Bug#168235: gcc doesn't link with profiled libc when -pg is used

[Andre Lehovich <andrel@U.Arizona.EDU>]

Package: gcc-2.95
Version: 2.95.4-7

The x86 version of GCC-2.95 doesn't link with profiled
versions of the system libraries when the -pg option is
invoked.  Here's a sample C program to illustrate the
problem:

#include <stdio.h>
#include <math.h>

int
main(int argc, char *argv[])
{
    double x = sqrt(M_PI);
    printf("x = %f\n", x);
    return 0;
}

upon executing "gcc -pg foo.c -fprofile-arcs -lm && ./a.out"
the file ./gmon.out will be created, which can then be
examined with "gprof ./a.out".  Notice that time spent in
sqrt and printf has not been recorded.  (I'm not including
gprof output because it is so long.)

A partial workaround is to use "gcc -pg -fprofile-arcs foo.c -lm_p",
which will detect time spent in sqrt, but not in printf.
Using "gcc -pg -fprofile-arc foo.c -lm_p -lc_p" produces the
following error:
/usr/bin/ld: BFD 2.12.90.0.1 20020307 Debian/GNU Linux
assertion fail ../../bfd/elf-strtab.c:262

I consider this to be a gcc problem, not a binutils problem,
because traditionally the -pg option to cc has caused the
profiled libc to be linked and both the gcc and gprof info
pages imply gcc is supposed to do the same.  Furthermore, I
can use "gcc -v" to find out how gcc invokes the linker and
edit that line to use -lc_p instead and get the correct
behavior, without ld failing any assertions, i.e. gprof also
reports the stats on printf.
