[PATCH, RESEND 1/2] kbuild: introduce HDR_ARCH_LIST for headers_install_all

[Kirill A. Shutsemov]

From: Kirill A. Shutemov <kirill@shutemov.name>

Using HDR_ARCH_LIST you can specify subset of architectures you want to get
headers for.

[PATCH, RESEND 2/2] kbuild: export linux/{a.out,kvm,kvm_para}.h on headers_install_all

[Kirill A. Shutsemov]

From: Kirill A. Shutemov <kirill@shutemov.name>

Export linux/a.out.h, linux/kvm.h and linux/kvm_para.h on
headers_install_all if at least one architecture has appropriate files
in arch-dependent headers.
