SUMMARY = "C library for embedded systems"
DESCRIPTION = "The name uClibc is an abbreviation for 'the \
microcontroller C library'. For simplicity, uClibc is pronounced \
'yew-see-lib-see'. The goal of uClibc is to provide as much \
functionality as possible in a small amount of space, and it is intended \
primarily for embedded use. It is also highly configurable in supported \
features, at the cost of ABI differences for different configurations. \
uClibc has been designed from the ground up to be a C library for \
embedded Linux. It is NOT compatible with binaries linked against glibc."

# For the compiler to work we need a working libc yet libc isn't
# in the sysroots directory at this point. This means the libc.so
# linker script won't work as the --sysroot setting isn't correct.
# Here we create a hacked up libc linker script and pass in the right
# flags to let configure work. Ugly.
