 locally define path_max is not available
 The code unconditionally uses PATH_MAX, which is POSIX-optional.
 .
 This fixes the build on platforms without it, such as GNU/Hurd.

 let bison generate the header directly
 Starting with Bison 3.7, the generated C   file #include's the header
 by default, instead of duplicating it. So we should not delete it.
 .
 Remove the code to add #ifdef guards to the header, since Bison adds
 them itself since version 2.6.3.

 fix jscore segmentation fault on 64-bit big endian systems
 In CodeBlock.cpp the code preparing the operands of op_get_from_scope writes
 the property offset as pointer size (hence 64 bit) value:
 .
 2141: instructions[i   6].u.pointer = reinterpret_cast<void*>(op.operand);
 .
 while the same slot is accessed later by the jitted code as 32 bit integer:
 .
 macro getProperty(slow)
    loadisFromInstruction(6, t1)
 .
 This fails on big endian targets since the integer access takes the higher
 part of the 64 bit value.
