[Buildroot] [PATCH] package/sysprof: propagate ucontext-related dependency from libdex

[Buildroot] [PATCH] package/sysprof: propagate ucontext-related dependency from libdex

[Thomas Petazzoni via buildroot]

BR2_PACKAGE_SYSPROF selects BR2_PACKAGE_LIBDEX but did not propagate:

	depends on BR2_TOOLCHAIN_HAS_UCONTEXT || \
		BR2_PACKAGE_LIBUCONTEXT_ARCH_SUPPORTS

from libdex. This commit fixes this missing dependency. In terms of
Config.in comment, we do the same as what libdex is doing: handle it
as a toolchain dependency (rather than an architecture dependency).

This was missed in commit a73ef093f7b40297d69c6813c44fd4626883632e,
which added the ucontext related dependency to libdex, without
propagating it to sysprof.

Fixes: a73ef093f7b40297d69c6813c44fd4626883632e ("package/libdex: needs ucontext")
