eglibc: enable support in the Buildroot toolchain backend
Using the newly introduced 'eglibc' package, this commit enables the
option of building a toolchain using the eglibc C library in the
Buildroot toolchain backend.
In details, this commit:
* Creates a choice to select uClibc or eglibc in the Buildroot
toolchain backend (in toolchain/toolchain-buildroot/Config.in), and
removes the fact that the Buildroot toolchain backend forcefully
enables uClibc (toolchain/Config.in).
* Creates a BUILDROOT_LIBC variables, which points to the package
implementing the C library (i.e either 'uclibc' or 'eglibc').
* Modifies the gcc-final and gcc-intermediate makefiles to use the
BUILDROOT_LIBC variable instead of hardcoding the use of uclibc.
* Ensures that TLS support is always enabled when building eglibc.
[Peter: fix commit text to refer to BUILDROOT_LIBC]
