configure.sh: Respect CFLAGS from the environment

Currently, configure.sh does not inherit any cflags from the
environment. However, for MIPS, it's necessary to pass additional
cflags to decide, for example, if we want a big endian (-BE) or
little endian (-EL) build. As a result of which, we modify the
configure.sh script to respect additional cflags passed by the
user.

maps: Rename MAP_{GLOBAL, LOCAL} to TRINITY_MAP_{GLOBAL, LOCAL}

The MAP_LOCAL flag is actually a valid flag and some architectures
make use of it according to the mmap manpage. More specifically,
MIPS and Xtensa define the MAP_LOCAL flag in their userpsace mman.h
header leading to build problems like this:

In file included from syscalls/mprotect.c:6:0:
include/maps.h:8:0: error: "MAP_LOCAL" redefined [-Werror]
 #define MAP_LOCAL 2
 ^
In file included from syscalls/mprotect.c:4:0:
/toolchain/mips-linux-gnu/libc/usr/include/asm/mman.h:37:0:
note: this is the location of the previous definition
 #define MAP_LOCAL 0x080  /* Copy on fork/sproc */
 ^

Therefore, we rename the definitions in trinity to avoid conflicts
with the linux headers.
