[Wien] siteconfig Wien2k 12.1

[Gavin Abo]

Dear Prof. Blaha,

Wien2k 12.1 users might encounter the error:

remotecp: Undefined variable

When n is chosen for shared memory in the parallel setup, the 
siteconfig_lapw script changes "set remotecp" to "set remote" in the 
vec2old_lapw script.

Can you please check if changing

sed -e "s/set remote.*"'$'"/set remote = $input/" <vec2old_lapw >tmp

to

sed -e "s/set remote =.*"'$'"/set remote = $input/" <vec2old_lapw >tmp

is the appropriate fix (i.e., adding the " =" after "set remote")?

It is noted that the vec2old_lapw script after expanding the source 
files, but before running ./siteconfig, must be used for the above 
change to work.

Thanks,

Gavin
