[uml-user] Debian "modify_ldt_ldt_s undeclared" problem fix

[BlaisorBlade <bla...@ya...>]

Debian (IIRC, the unstable one) has started putting 2.6 headers in 
/usr/include/asm, and this has given a compilation error with UML. Attached 
there is a fix for 2.6, which makes the source detect and use the correct 
structure name. So this patch doesn't hurt who hasn't that problem.

For 2.4 I'm not attaching a fix since the code has been commented out in 
2.4.23-1um (the comment says this doesn't work in TT mode, but making the 
code a no-op for TT mode is easy). The idea comes from the hostfs Makefile.

Bye
