[PATCH v5 02/27] x86: Use symbol name on bug table for PIE support

[Thomas Garnier]

Replace the %c constraint with %P. The %c is incompatible with PIE
because it implies an immediate value whereas %P reference a symbol.

Position Independent Executable (PIE) support will allow to extend the
KASLR randomization range 0xffffffff80000000.
