[LTP] [PATCH 2/2] build.sh: support compiler with path prefix

[Li Zhijian]

Previously, specify a compiler with path prefix will lead to a error
like below:
ltp$ ./build.sh -t cross -c /opt/gcc-4.9.3-64-gnu/bin/mips64el-linux-gcc
...
It was created by ltp configure LTP_VERSION, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure --with-open-posix-testsuite --with-realtime-testsuite --prefix=/home/lizj/ltp-install --host=/opt/gcc-4.9.3-64-gnu/bin/mips64el-linux
...
 #define VERSION "LTP_VERSION"

configure: exit 1
