scripts: leave changelog in build dir, copy to install dir

Users tend to look for the build log in the current working directory,
rather than in the toolchain's installation dir. While bundling the build
log in the toolchain installation dir is nice for distribution and review,
it can be easier to have the build log readily available in the working
directory, as it is quicker to get to it.

So, the build log stays in the working directory until the toolchain is
completely and successfully built, and then a (compressed) copy is made.

     1 This patch is needed on newer uclibc becuase the uclibc header generation

     2 mechanism generates the sysnum.h properly NR_cacheflush is defined for ARM

     3 but there is no cachectl.h file which is exported to userspace. Strace 

     4 assumes that if SYS_cacheflush is defined than it icludes asm/cachectl.h

     5 which breaks the build for ARM now.

     6 

     7 This patch adds a check for ARM architecture.
