Try to file2c(1) utility. Quoting from its manpage:
% EXAMPLES
% The command:
%
%date | file2c 'const char date[] = {' ',0};'
%
% will produce:
%
%const char date[] = {
%83,97,116,32,74,97,110,32,50,56,32,49,54,58,50,56,58,48,53,
%32,80,83,84,32,49,57,57,53,10
%,0};

I think there's something wrong with the converter, then. The file2c(1)
utility converts my kernel (6 MB of data) in less than 3 seconds:
$ /usr/bin/time file2c 'const char kernel[] = {' '};' \
< /boot/kernel/kernel > /dev/null
2.98 real 2.92 user 0.11 sys
