elfutils_0.148.bb: Fix compilation on uclibc

Currently all components of elfutils dont compile with uclibc
but elfutils is one part which is needed by other recipes e.g.
gcc 4.5 to compile. we make adjustments so that when compiling
for uclibc targets it _only_ builds and packages libelf

use --enable-uclibc only when building for uclibc targets

The supporting patch is also needed for compiling with uclibc
to specify -lintl and -luargp on linker commandline

Add missing inherit on gettext

+on uclibc systems libintl and libuargp are separate from libc.
+so they need to be specified on commandline when we use proxy-libintl
+then libintl is a static archive so it should be listed last since
+elfutils does not respect disable-nls we need to link in libintl
+
+We add a new option --enable-uclibc which will be used to control
+the uclibc specific configurations during build.
