Don't munge yacc's #line directives
The #line directives within GDB's autogenerated yacc files (e.g. c-exp.c) are being incorrectly munged, causing these directives to refer to nonexistent source files, e.g. #line 36 "/home/patrick/binutils-gdb/gdb//home/patrick/binutils-gdb/gdb/c-exp.y" as opposed to #line 36 "/home/patrick/binutils-gdb/gdb/c-exp.y" The munging happens due to a sed expression added by commit 954d8cae whose intended purpose[1] was to work around the fact that ylwrap emitted #line directives without any directory information, e.g. #line 36 "c-exp.y" So the sed expression was meant to munge such directives to refer to absolute paths instead. But the behavior of ylwrap was changed some years ago[2] to emit absolute paths within #line directives. And when our local copy of ylwrap was synced by commit e30465112, the sed expression in question became unnecessary, and indeed harmful. This patch removes the now-obsolete sed expression. The emitted #line directives are now correct without it. gdb/ChangeLog: * Makefile.in (.y.c): Don't munge yacc's #line directives.
