Subject: meson: also try to search gnu-efi based on EFI_MACHINE_TYPE_NAME (#8900)
X-Git-Tag: v239~312
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4b4ee0f781f6eaeb5c0dc8e2f9ea65ff8414356c;p=thirdparty%2Fsystemd.git

meson: also try to search gnu-efi based on EFI_MACHINE_TYPE_NAME (#8900)

On Fedora rawhide, since gnu-efi-3.0.8-3.fc29, many file paths are
changed to use `EFI_MACHINE_TYPE_NAME` instead of `gnu_efi_arch`.

Fixes #8896.
