Due to a misplaced parenthesis, the libunwind dependency were incorrect. Indeed, they were of the form: default y if LIBC_TYPE && (arm dependency) || (list of other architectures) Which meant that that the LIBC_TYPE dependency was not taken into account for the "other architectures". This commit changes that to: default y if LIBC_TYPE && ((arm dependency) || list of other architectures) Without this fix, libunwind can be selected for example on PowerPC/uClibc configurations, while only PowerPC/glibc should be allowed. This fixes: http://autobuild.buildroot.net/results/96c53ff240dcd68fcc9e3d32c4026c9886edcbe7/ Similarly, it also fixes cases where SuperH/uClibc was allowed, while only SuperH/glibc should be allowed.

# In addition to this, on some architectures libunwind requires the

# *context() function from the C library, which are only available on

# certain architectures in uClibc, and not available at all on
|
|
# musl. But on some other architectures, libunwind works without using

|
# the *context() functions, which allows it to be built with musl.
