When using MKTEMP_EACH_FILE for GCC 2.3.3 with DBX debugging info, GDB
no longer works correctly as it explicitely checks for ".o" at the end
of symbols.  For instance, the backtrace command is affected.

Quotation from partial-stab.h of GDB 4.7:

	  if ((namestring[0] == '-' && namestring[1] == 'l')
	      || (namestring [(nsl = strlen (namestring)) - 1] == 'o'
		  && namestring [nsl - 2] == '.')

(BTW this is a bad idea if the length of namestring is less than 2.)

I solved the problem by letting ld append `.o' to the symbol
indicating the start of the text segment unless that symbol starts
with `-l' or already ends with `.o'.  (I'm still using the pre-BFD
version of GNU ld.)
