The toolchain, arm-elf-tool include an old uClibc and another toolchain, 
arm-tool does not includ uClibc, but it does not matter. uClinux will 
link the library under it's root directory. So these two toolchains link 
the same uClibc under uClinux-dist directory. I did some tests and I 
found that elf2flt cause the problem. I used elf2flt in arm-tool 
toolchain to replace elf2flt in arm-elf-tool toolchain, and sigsetjmp 
can be called now. I do not hack the souec code of the elf2flt, so I 
still do not know the reason.
