Only add it to LDSHARED. This BLDSHARED/LDSHARED stuff had me baffled 
for a while, but it turns out to be really simple: BLDSHARED is used 
only when building an extension module during the normal core build 
process (hence the "B"), and LDSHARED is used otherwise (i.e. when using 
distutils on an already installed Python). To make understanding even 
more difficult some of the rules that makedepend added to the makefile, 
which turn out not to be used anyway, use LDSHARED where they should use 
BLDSHARED.
