gdb: avoid unnecessary string copy in auto_load_objfile_script_1
Assigning the result of STRIP_DRIVE_SPEC to an std::string creates an
unnecessary copy of the string. STRIP_DRIVE_SPEC is defined as:
#define STRIP_DRIVE_SPEC(f) ((f) + 2)
So if it is passed a "const char *", it returns a "const char *". We
could use a "const char *" intermediary variable instead of an
std::string, or (as implemented in this patch) just use it directly in
the concatenation right after.
gdb/ChangeLog:
* auto-load.c (auto_load_objfile_script_1): Don't use
debugfile_holder as temporary variable when stripping drive
letter.
