[PATCH] Fix headers_install for x86-64 (now with less whitespace damage!)

[Rob Landley <rob@landley.net>]

Signed-off-by: Rob Landley <rob@landley.net>
 
 A bug in headers_install for ARCH=x86_64 yields an asm/ directory full of
 files all of which are using the same #ifdef guard, "__ASM_STUB_" with no
 postfix. So the second and later asm files #included in the same C file
 (often through standard headers like ioctl.h) yields no symbols.

 There's a missing semicolon after the assignment to FNAME (so the assignment
 of STUBDEF on the next line doesn't see the value), and it helps to export
 variables before calling a subshell.
 
 Second try, telling Kmail not to wordwrap inappropriately.  (I am up waaaay
 too early to get ready for OLS...)
