Sonic Zhang 170d526e91 icu: detect and add compiler symbol prefix to the assembly code 
Some compilers, such as the Blackfin GNU compiler, prefix a character to any
C symbol in generated assembly code. If any assembly symbol is invoked
from C code, it needs to be prefixed as well.

Note: since autoreconf doesn't work with this package because automake
isn't used.

Fixes:
  http://autobuild.buildroot.net/results/c40a22814b405de2c5c75139cfc393c863ed4b81/

[Ryan: add information about why patching configure is ok]
[Ryan: add renaming of patches to be consistent with standard]
