[ARM/FDPIC v6 02/24] [ARM] FDPIC: Handle arm*-*-uclinuxfdpiceabi in configure scripts
The new arm-uclinuxfdpiceabi target behaves pretty much like
arm-linux-gnueabi. In order to enable the same set of features, we
have to update several configure scripts that generally match targets
like *-*-linux*: in most places, we add *-uclinux* where there is
already *-linux*, or uclinux* when there is already linux*.
In gcc/config.gcc and libgcc/config.host we use *-*-uclinuxfdpiceabi
because there is already a different behaviour for *-*uclinux* target.
In libtool.m4, we use uclinuxfdpiceabi in cases where ELF shared
libraries support is required, as uclinux does not guarantee that.

* futex.m4: Handle *-uclinux*.
* tls.m4 (GCC_CHECK_TLS): Likewise.

* configure.tgt: Handle arm*-*-uclinux*.
* configure: Regenerate.

* config.host: Handle *-*-uclinuxfdpiceabi.
libitm/
* configure.tgt: Handle *-*-uclinux*.
* configure: Regenerate.
* libtool.m4: Handle uclinuxfdpiceabi.
