gprofng: fix 32892 source line level information not available with "-g -O2"
gprofng ignored DW_AT_specification.
As a result, gprofng skiped Dwarf for all functions declared as:
< 2>:<0x0000f725> DW_TAG_subprogram(46)
DW_AT_linkage_name(110) "func_name"
DW_AT_declaration*(60) 0x1 (1)
< 1>:<0x00015acc> DW_TAG_subprogram(46)
DW_AT_specification(71) 0xf725 (63269)
Another problem was that gprofng ignored DW_AT_ranges.
As a result, many functions are mapped to the <Unknown> module.
