From: Arnout Vandecappelle (Essensium/Mind) Date: Sat, 24 Jul 2021 21:45:25 +0000 (+0200) Subject: package/lapack: introduce BR2_PACKAGE_LAPACK_ARCH_SUPPORTS X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d2453aa83d8f7d394b3dbe33472e5f1642268a63;p=buildroot.git package/lapack: introduce BR2_PACKAGE_LAPACK_ARCH_SUPPORTS This makes it easier for packages that depend on lapack to get their dependencies correct. The !uClibc dependency is also not sufficient: indeed, musl too does not provide _fpu_control; only glibc does. This is the same situation as for clapack. Add a comment about this, to mirror clapack. Since the !glibc dependency only exists for PowerPC, treat it as an architecture dependency.
