klibc_1.5.18: Fix the build for x86 on newer kernels.

* We were setting KLIBCARCH to match kernel arch
  while this let klibc build, it did not configure
  in right syscalls because klibc still use 'i386'
  the patch tells klibc to look for right places in
  kernel tree based on arch and we can stop synthesizing
  KLIBCARCH to be same as kernel arch.

+On newer kernels the arch dirs for x86 and x86_64 are merged into x86
+but klibc does not know that. This patch teaches it where to look at
