running a manual sed on it wouldnt uglify it.  the contents wouldnt
change at all.  as long as the current style is adhered to, it's quite
trivial.

in the Makefile.am:
libgcrypt.vers: libgcrypt.vers.in
    sed -r 's:\<(gcry_):@SYMBOL_PREFIX@&:g' $< > $@

well, some clarifications here:
 - Solaris does support symbol versioning and if my history is
correct, it had it before the GNU toolchain
 - Blackfin only supports uClibc because glibc isnt interested in
supporting nommu systems, and uClibc does not support symbol
versioning
