[Bug 2040041] [NEW] -pg does not generate gmon.out file

[Skewray]

Public bug reported:

compiling with -pg has two issues. First, many "gcov" routines are not
found during ld. I fixed this by adding "-L/usr/lib/gcc/x86_64-linux-
gnu/12 -lgcov" to the ld command. That's pretty arcane. Second, the
program generates .gcda files, but not the gmon.out required by the
"gprof" command.

The manual entries for gcc and gprof do not imply that this
functionality has been removed or altered.
